The Bishop Conklin Company, makers of paint, is a Los Angeles concern I'd never heard of. Their building at 3951 Medford St in East L.A. still stands, now the home of Studio 3951, designers of "retro-modern accessories, knits, jewels."
The top photograph above was taken by Maynard Parker, whose work we've seen before. I wasn't aware that more of his work is now available online at the OAC:
