W.L. Larry Baker QSL card

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?).
