That would the symbol for the conjoined version of Mal Duncan and Firestorm after the Zeta Beam accident...
Artist-creator Dave Stevens, best known for chronicling the adventures of '40s-era hero The Rocketeer, was taken into the clouds by his hero and has not been seen since.
Close friends say Stevens had suffered from a serious health problem in recent years, but that it didn't affect his optimistic, upbeat way of seeing the world.
An artist and illustrator since the mid-1970s, Stevens, 53, enjoyed professional success working on the Tarzan comic strip with Russ Manning. He also worked in comic book illustration for years, before developing a long-lasting friendship with Cliff Secord (aka The Rocketeer), whose adventures Stevens brought to life in a number of publications.
A film was made of The Rocketeer's earliest exploits in 1991 by Disney.
Bugles Planet Daily wishes to extend its condolences to Stevens' family and friends.
