WGBF Back In Tha’ Day!

This is a postcard I found on E-bay.  Apparently this used to be the WGBF morning show back in the WW1 era.  Here's the sellers e-bay description of the item.    "Original real photo postcard or also called an RPPC of the Morning Worship Quartet over WGBF am in Evansville Indiana. The postcard has an AZO Stampbox on the photocard postcard back indicating a printing around WW1 - 1920s. It is in excellent shape with only minor wear on the back. Nice sharp detail in the image! Probably a hard to find card from this area. "         I'm afraid if we had these folks on in the morning show now, we wouldn't be treated to things like "Dicken's Cider" and "Pinkley Taurus" as we are now with The Bob and Tom Show!
