Getting QSL cards in the mail has traditionally been an exciting part of Amateur Radio, as immortalized here on the cover of QST 100 years ago this month, July 1923.
The artist is Clyde Darr, 8ZZ, who provided at least 69 such illustrations for the magazine prior to his death in 1929 at the age of 50.
1923 was an exciting time to be a radio amateur. The technology was relatively new and two- way contacts were not a sure thing. Especially DX. So when they occurred, it was special and a QSL card was an achievement. Great art work. Very nostalgic.
