Each is 1.25” without backpaper but with union bug stamped on reverse. Both feature the same inscription “I Helped The Municipal Tree.” On one, Santa flies a bi-plane with huge toy pack and a decorated Christmas tree lying on the top wing. Second shows him driving auto towards the viewer again with toys and tree. Text on this one just a hair off-center to the right. This is only the third bi-plane example we’ve seen and the second in the car. The first time we offered this pair way back in Auction #154, they exceeded $1,100. Each is in essentially Mint condition with bright colors and high gloss. Also see rare Santa button by R. Crumb #1518.
