* If your scratching your head why I started at 1946, if the attendance awards started in 1927.
1. Supply and Demand, 1927-1945 are  very hard to find, every now and then they show up on E-bay but  go for big bucks.
There is one website that show the 100% attendance pins in there entirety at
Lions International Trading Pin Club  at  http://www.litpc.org/index.html.
2. All pins are from my collection, and I have 22 years of perfect attendance. BK
