Nothing on the back except, "Printed in Japan".
Generously donated to the Filmic Light by the Michael Filippello Collection.

A second Snow White 3D postcard is shared here from the Nunziante Valoroso Collection. Manufactured by Toppan Top Stereo and printed in Germany.
Nunziante mentioned that while these lenticular cards date from the 1960s, they were also reprinted in very recent years. "Not hard to still find them here in Italy in some shops."
Special thanks to Michael and Nunziante for sharing their Snow White postcards with us.
