Very talented organist
I think it’s real. Raymond Daniel Manzarek - Born 2-12-39.
Would you say an old signature from the 70s or 60s?
Not 60's or 70's. It looks like a later signature.
The white cards are throwing me off. It's an older thing to do to write ray organist at the bottom of the card .
It is very bright and under contrasted. There is "Founder of Doors" in pencil erased and other things - possibly paper loss as well. I will go to the other room and try and show what it might look like.
I find I like the period notations, especially dates/locations, on these vintage signed cards/slips etc.
That seems problematic...
You got it pal esp when asking 10k.
The Dave Grohl Foo Fighters notation was probably added after 1993. Not good for $10k set!!!!
