Antique Unused German Mechanical Valentines Day Card Page Boy Carrying Cake

Wonderful antique mechanical Valentine’s Day card circa 1930s featuring a page boy carrying a cake on a golden platter. His hand and leg moves, and when you move his hand his eyes move around a bit! He’s in great condition, a little wear as expected with age. There is a light, small pencil mark where a past antique dealer wrote their number and price. I didn’t risk erasing it myself. 7 inches tall by about 4 inches wide.
