So what exactly did you buy? A poster? Three comics?
Reminds me of the Big Bang Theory episode I watched last week, where they go to a costume party as several superhero characters. Exactly the first five chracters from the left in the second pic, plus Batman.
They are three different panoramic posters that I merged into one image to post here. They are reproductions of the super hero characters I watched each Saturday morning as a kid, the Super Friends.
Top pic is "All New Super Friends".....Superman, Wonder Woman, Batman & Robin, Aquaman, and in the center, their trainee heros, the Wonder Twins, who were shape-shifters. (1976-1977)
The middle pic was the next season (1977-1978) "Challenge Of The Super Friends". Heroes were added to make the cartoon similar to Justice League, and three "ethnic" heros were added to break up the "whiteness" of the show. However, the ethnic heros were given names that matched their ethnicity, and not their powers. The line up was (l to r) Superman, Wonder Woman, Aquaman, Flash (super speed) Green Lantern (power ring) Hawkman (flight and bird-like senses), Samurai (turns into wind, and becomes invisible), Black Vulcan (electricity), Apache Chief (grow to 50 feet tall) Robin & Batman.
The last pic is from the same series, the villains, The Legion of Doom. (l to r) Lex Luthor, Brianiac (super android), Mr. Freeze (freeze ray gun), Giganta (grows up to 50 feet tall), Bizzaro (reverse Superman), Grodd (super intelligent gorilla), Cheetah (cat like reflexes), Sinestro (yellow power ring) Riddler, Black Manta (undersea villain), Toyman (uses toys/gadgets for crimes), Scarecrow (master of fear) and Solomon Grundy (zombie super villain)
