Downtown Secret

The Town Lodge Motel sign hides a secret, there is a piece on the inside of the signage hidden from view.
It's a somewhat bizarre and textless mash up of Beatle John Lennon and former president John F. Kennedy.
Lennon wrote lyrics like "I don't believe in Kennedy" in 1970 for his song God (John Lennon song),
is there any connection between to the two men I am failing to see? Other than horrible assassinations
and jumbled conspiracy theories? Artist unknown on 7th street.
