This is a promotional postcard for Robert W. Morgan. The back of the postcard reads:
KHJ “Boss Jock” Robert W. Morgan
Don’t mess with this man ... he’s waiting for you on the Bossline! Phone KHJ at your own risk when Morgan’s at the wheel. What you don’t hear on the phone you get on the air: much more music with a cat that’s putting everyone on ... only try to get him to admit it.
