Though most fans know his 1940s-60s work on DC's Superman and Batman...
...Al Plastino had quite a varied output, ranging from Golden Age comics to almost becoming Charles Schultz's replacement on Peanuts!
Mark Evanier has a nice pro/fan tribute to Plastino HERE.
And, you can read about a recent controversy involving Al's long-missing art for a Silver Age Superman story featuring the late President Kennedy HERE.
As for me, I'd like to link you to a tale from Plastino's early days...and a character he co-created, which unfortunately went nowhere.
The wild thing about The Rainbow, is that he was one of the first comic characters inspired to become a super-hero by reading a comic book!
Have a look HERE.
