Finally a puzzle I can relate to! This trip down memory lane features nine references to things dated before 1970.
Thingamajig GISMO [When was the last time you heard GISMO --- or "thingamajig" for that matter? "Thingy" may be in today.]
Borax haulers, in classic ads TWENTYMULETEAM [big sponsor in '50's TV]
Sal of "Exodus" MINEO
Lash of old oaters LARUE [cowboy whose weapon was a whip]
Sonny and Cher song, e.g. DUET
Be a rat fink TELL ["Rat fink" was a hippie term.]
"Animal Farm" author George ORWELL [his book was old in 1984]
Etiquette author Post EMILY
"The Thin Man" dog ASTA [There was a 50's TV show (Peter Lawford) based on the 40's movies (William Powell)]
I have no idea what TCB stands for.
