Looks to be a QSL card from Charles F. Makowski who lived at 1020 Ninth Ave. E. according to American Radio History. These were mostly used to track communications over ham radio. They were often sent to other operators as a written confirmation of communication. It was a little like a calling card for an amateur station. Charles was communicating with one Norman W. Fincher who lived in Atlanta. His call sign was W4FIJ. Gozinda and Gozouta are bal­anced and unbalanced input/output structures that were utilized to maintain the conversation. The line at the bottom is called a Q code and breaks down as follows: VY=Very, 73 is a typical short code for "best regards," and comes from the Phillips Code which was used for telegraph operators before ham radio. A QSO is essentially a contact with a person. QSL means "Can you acknowledge receipt?" Pretty neat stuff, thanks for sharing!
