Looking for advice from the experts. I am an adult boy scout leader and have lots of insignias from my youth. I would like to use one of these as a temporary insignia for my right uniform pocket to help generate conversation points with our scouts. I have two on which i would like input. The first is 2.5in w x 4in h patch that says "America's Bicentennial festval USA 1975-1977" it has an American flag and a scout logo. The second is from a year I lived in Belgium as a 2nd grade cub scout, it is round and 2.5in in dia and it says " TransAtlantic Council BSA" overlayed on a map of Europe. Would either of these fit the rules for temporary insignia? and if they both do, which would you choose to wear? Thanks!
