1920s to 1960s art or letters

Tonawanda NY

Description

I recently went through my great grandfathers old belongings and found, his family left behind artwork and letters from 1922. I found he was offered to be part of a secret society, free masons. As well as he was threatened by the (possible)k k k through letters. I am now deep into learning more about the history of the US NY and would appreciate any artwork or letters from before the 1960s or 1950s or information, stories you'd be willing to share. Thank You
