The usual variety of this is 2-1/8" with an orange rim. This is the scarcer 1.75" with yellow rim. Last couple we've seen are without backpaper and we think that is as it was issued. Back of this has had some brown oxidation polished out but this causes no problem. Celluloid is totally clean and Exc. although a few scattered pinpoint bumps will catch reflected light. Displays Mint.
