Along with the two photos was this copy of the Frost Obituary. The "Batlin' Bet" is visible behind him. This could very well be amongst the last paintings Frost painted.
My thoughts: Find where He's buried. I wondered if anyone from his family was still alive? I thought, "there must be a death certificate on file..."
I contacted Forrest Lawn Cemetery in Glendale, and sent them a letter to pass on to his next of kin, (if they still existed). Then I made it a quest to locate his grave.
Ironically the Frost Grave was located approximately 100 Feet from my Uncle Bill's, and Bob Ketron's Grave site, (in the same cemetery).
This obituary gave me a great starting place for my quest.
