Teeming Team-Ups

Speaking of mixing styles (lame segue)...

We have one month to go on our Classic DC Covers wall calendar. This month's was the great Flash-Superman race cover (Superman #199, 1967) with art by Murphy Anderson and Carmine Infantino. The mix of their distinct styles reminds me of covers here.

Also:
15 Impossible Superhero Crossovers (That Actually Happened) - meh team-ups compared to what we're used to here, but more proof Ross taps a vein (daily!) everyone enjoys.
