Three Early Post War Japanese Menko Cards-Flying Bird w/ Pilot and Dog, 2 Others

This lot of three menko cards definitely has the early colors used by the Japanese in the early post war period.
Each card has images on the front, but nothing printed on the back.  The cards are each 2 and 5/8 inches ( 6.7 cm) in diameter.  Condition is very good to excellent with no wear.  Colors are intense.

The images on these menko cards show up again and again but I don't really know much about the characters. There is a boy pilot flying on a bird with his puppy...he appears to be shooting at a train far below. The card showing a stove and boy and dog climbing out while a bearded old man observes is also seen fairly often. The final card shows two characters: a monkey and a bird beaked creature.

You are buying the lot of three menko cards for one price.
