This ham radio QSL card from around the late 1940s uses an eclectic mix of period typefaces. The big type for “W6ND” is Glamour Bold (c.1948). “Burlingame, California” at the top is in George Salter’s Flex (1937), and Lindsay’s name features Keynote (1933) by Willard T. Sniffin. The form labels are set in the upright style of Piranesi (1930), also by Sniffin. Unlike Benton’s Piranesi Italic, it hasn’t been digitized yet. The bolder line in the bottom left corner uses the similar Bernhard Modern (1937).

This QSL card for U.S. Navy sailor (and ham) Jack H. Reese makes strong use of Neon (and a ferocious engraving of a bald eagle). Supplemental text front and back is set in Kabel (or Sans Serif). Note that the diamond shaped ARRL logo is still in use as of 2020.

This QSL card features the kräftig and fett weights of Erbar-Grotesk. It documents a contact from 5 January 1979, but it could have conceivably been designed years, or even decades earlier. The call sign seems to mix in glyphs from another heavy sans which, despite the characteristic 2, hasn’t been identified yet.

The bold serif on the back of the card appears to be Aurora (or Corona?).
