Backward Advances: Rear-Facing Trombones Throughout History
Trombones have gone through more permutations than some people may realize. Not only has history seen soprano, alto, tenor, bass, contrabass, and valve trombones, but an intriguing permutation of the instrument, called the rear-facing or over-the-shoulder trombone, pops up frequently in pictures and occasionally in museum holdings; e.g., here. For a YouTube clip of someone playing such an instrument, see here. (I prefer rear-facing as a descriptive term, since over-the-shoulder does not distinguish from the standard trombone, which already has a rear bow of tubing that extends over the player's shoulder.)
The very earliest examples of this version of the instrument likely reflect the working-out of the shape of the trombone; the standard trombone evolved, after all, as a "bent" version of the original straight trumpet. The exact manner and shape of this bent tubing was almost certainly not immediately standardized, and it is highly likely that there was some experimentation along the way.
Beginning in the late 18th century, there was a more general trend among all brass instruments toward over-the-shoulder instruments (see Boston Brass Band example, below). Trombones were part of this trend, which is said to have been at least partially the result of the desire for better ensemble balance (i.e., these highly directional brass instruments became generally softer).
Historian David Guion categorizes over-the-shoulder trombones as "no more than a temporary vogue" (Guion, A History 66). I'm not sure I completely agree. It depends on how you define temporary, of course. There are nine images from pre-1800 alone. Even if you discount those nine early examples (and I fail to see why you should), you're still left with a long, steady stream of iconography after that: 61 additional images from 10 different countries spanning a full century. That is chronologically too long and too widespread to be considered a "temporary vogue." A temporary vogue that lasts a full century?
I would probably characterize it something like this: Iconography suggests that the over-the-shoulder trombone, which can be seen in a handful of images before the 19th century, became relatively widespread in the 19th century. Use of the instrument does not appear to taper off until the end of that century. Although there is significant variety in iconography, many of the images originate in France, and a large number of them depict military usage.

c. 1405—Paris, France: A grotesque from the Hours of Charles the Noble plays what is perhaps a proto-rear-facing trombone. There is no slide, obviously, so it is not a true trombone, but the similarity in general shape is obvious and could be seen as an early experiment in the direction of rear-facing brass instruments (see below image; public domain) (RIdIM/RCMI Inventory No. 8, p. 21).
1503-1529—Spain: A painting by either Joan Gascó or Gabriel Guardi includes an angel-trombonist playing what appears to be a rear-facing instrument. The first detail, below, shows the rear-facing bell, partially obscured by the halo, circled in red. The second detail shows more of the image, providing a view of the other halos and the materials nearby. Finally, the third image is the full painting (public domain image) (Ballester; French National Library).
c. 1504—Perpignan, France: A painting on an organ shutter (since relocated to the wall opposite the organ) in the Perpignan Cathedral (Cathedral Basilica of Saint John the Baptist of Perpignan, or Basilique-Cathédrale de Saint-Jean-Baptiste de Perpignan) depicts musicians at the Feast of Herod, including a rear-facing or over-the-shoulder trombone. Although there are some improbable aspects of the trombone, including the shape of the slide and the general configuration of the tubing, it seems unlikely that the artist would have misjudged the actual direction of the bell (see below detail; public domain; special thanks to Jean-Jacques Herbin).
1570—Waiting for the Princely Guests, an image depicting wind musicians in a balcony atop a triumphal arch, shows trombone, trumpets, bombard, and positive organ, as they prepare to play for a prince’s arrival (see below image; public domain) (Carter, Renaissance 278; Nuremberg, Stadtbibliothek).
1578—Antwerp, Belgium: A set of masses by George de La Hele includes a print–an initial D in front of a group of cherub musicians–that features a rear-facing trombone being played by a cherub (also rear-facing) (see below image; public domain; Wangermée vol. 1 167).

1689—The Netherlands: An etching by Dutch engraver Romeyn de Hooghe titled L’Europe Allarmée pour le fils d’un Meunier includes what appears to be a rear-facing trombone (see upper-left of full image). The print is a satire against James II (see below detail and full image below; public domain).
