true but it is still wallpaper.
So this is one of those unusual cases where we may both be correct lol. Here’s a vintage ad for the Cling-Foil product Fender used on these. One of the use cases mentioned for it is…. Wallpaper. I didn’t realize it was advertised (and presumably used) that way. I’ve always heard of it as the kind of stuff people put on kitchen shelves. Anyways, interesting bit of trivia…
