Vintage Japanese "Flying" Menko Card - Helmet Wearing Boy Hero with Gun

This flying menko card is so called because there are two notches in each card that when a rubberband is used can launch the card into the air. A depiction of a boy doing just that is on the box these cards came in. It is shown in the photos for informational purposes only (it is not included in the sale).

The colorful menko card is 2.75 inches (6.9 cm) in diameter.  Two helmet wearing characters (one has a gun...police?) and a small red dressed professor with a mustache are on the front of the card along with the hand sign, Japanese writing and number.  The back of the card has a large hand sign along with a number and two Japanese characters.

Condition is very good to excellent. The backs of the cards have some age related foxing and stains.
