Did some newspaper/archives searching and came across the following:
An article in the Times-Picayune [New Orleans] of 1969.Sep.06 about, then 18 year old, Philip Core:
"He [Philip Core] is planning illustrations for several books, and a portrait he did of the lead singer of Andy Warhol's group, The Velvet Underground, led to a friendship with the singer and an acquaintance with Warhol."
Wiki about Philip Core https://en.wikipedia.org/wiki/Philip_Core
His painting of Andy Warhol and Marcel Duchamp at https://artuk.org/discover/artworks/the ... hamp-63268
Searched for Lou Reed/Velvet Underground in connection to Philip Core, but without any serious result.
Anybody know anything about the in the 1969 article mentioned portrait?
