Card Size: 2 9/16" x 3 3/4"
Notes: No manufacturer identification on these cards, blank backed. I got them from Canada, so they may have been issued in that country. I also think these were issued in Europe, probably Belgium, possibly other countries.
These were apparently issued by Leaf Sales (Confectionary) Inc., though there is no mention of the issuing company on the cards. This is a different Leaf than the Chicago-based Leaf. The cards were issued in gum packs, 3 cards plus one piece of gum. The title of the set on the packs was Famous Artistes Series.
Thanks to Mike Maltzman, Mark Edmunds, and Carlo Maria Allochis for help with this checklist.
