Vymura was a British product developed by Imperial Chemical Industries in the early 1960s (see an ad here). The vinyl wallpaper was extremely popular throughout the decade because it was durable and washable, unlike standard wallpaper.
The ad is 18″ x 23″, and the wall vinyl is actually a mural (something like 4′ x 6′). Vymura also released Star Wars and Empire Strikes Back wallpaper that I’ll post later. Both featured beautiful original designs.
