JRM 6: 1949 Flying Menko

JRM 6: 1949 Flying Menko is the first of these menko sets (in numbered catalogue order) that features a unique back. I have scanned the pages in my collection, so when backs are shown, they will be in rervese order (right to left backs). This set probably is harder to find in decent shape, as the notches were used to slingshot the cards via ruber bands. This set has 12 cards, 1 5/8" diameter.
