Uncle Joe had sent this letter to a cousin... it indicates his frustrations as a struggling artist and, in general,  a misfit in this world.  He died in 1986.  He gives some detail about his process, outlining his technique in various art forms:

• leather carving
• pen & ink drawings (E.g., "A Brief Pause" and "Forever Giving")​​

I wish I could hang out with my Uncle and make art together.  I wish he knew how loved he was, though perhaps he knew, but it wasn't enough.

"A Brief Pause"
