Ah, fond memories of my childhood, hot summer days when my thirst would be quenched by an ice-cold Slurpee... and for one glorious summer, those Slurpees came in plastic cups featuring Superman and other DC characters!
Jonathan Kent and Perrry White appear in this group of cups!
This group includes Superboy, Lana Lang, Jor-El & Lara, and Jimmy Olsen!
I think these need no further explaining:
Yep, that was the summer of '73!
