Grafiche Biondetti, manufacturer of the Italian postcards seen in the previous post, also produced a series of Disney postcard stickers (adhesives) utilizing the same artwork. Just two of the Snow White cards were made into stickers--Snow with her forest animals and the Dwarfs crossing the log. These were first issued in the 1970s with later reprints. The cards below date from the mid to late 80s.
Thanks again to Nunziante Valoroso for providing the postcard images and info.
