I've not seen any pop-ups, and if/when I do, they annoy me, so I just 'x' them closed without bothering to look at the subject matter.
However, I've known about "La Vache Qui Rit" for many, many years. They've been around quite a long while; at least 25 years. It is very good cheese, but no longer in my budget, for the packages only have about 5 small wedges and the price point is too high for my current situation.
They also used to be available in small boxes of individually foil-wrapped cubes about 1/2 inch square.
