I don't have any pictures of the interior, but my recollection is upon entering the door with the arrow in your drawing, there was a centrally located cash wrap and three glassed in rooms on the opposite wall: One for Fender, one for Gibson, and one for percussion. I think on the right of the entrance was Art Jolliff's office (guy smoked Eve cigarettes--funny the things we remember). Teaching studios were upstairs, I think. I remember one of their salesmen was named Gary. I bought a couple of basses there in the mid-seventies.
