This is one of my favorite images of the Manhunter from Mars, a lovely postcard I picked up on eBay about a decade ago. I used to feature it prominently on my old "Martian Manhunter: The Rock of the JLA" site, along with the two articles Who is the Martian Manhunter? and J'Onn & Me. In light of the Idol-Head of Diabolu's upcoming 600th post and the postcards' being reprinted shortly in the DC COMICS CLASSICS LIBRARY: THE JUSTICE LEAGUE OF AMERICA BY GEORGE PEREZ VOL. 1 HC, I thought it was about time I stopped hoarding the piece away from the internet. The return of the articles will keep.
George Pérez produced 16 postcards for the unnumbered JLA set. Also featured were the Sword of the Atom (Ray Palmer,) Aquaman, Batman, Black Canary, Elongated Man (& Sue Dibney,) the Flash (Barry Allen,) Firestorm (Ronnie Raymond,) Green Arrow, Green Lantern (Hal Jordan,) Hawkman (and Hawkgirl, of Thanagar,) the new Justice League of America (Detroit Era members Steel II, Gypsy, Vibe and Vixen,) Red Tornado, Superman, Wonder Woman and Zatanna. You can view signed versions of all the cards here.
