Marvel Mix-tape Convention Edition 2011
Due to the recent announcement of a new solo Venom film speculators and collectors have been wondering which incarnation of Venom we will eventually see on the big screen. Anything is probably going to be better than what Topher Grace and Sony offered in Spider-Man 3. In this case there is a second character to consider thanks to an excellent series from 2011, Flash Thompson. So when did Flash first appear as Venom? Currently ASM 654 is considered his first. His origin was presented as a backup story and was probably the most creative thing done with Venom since his inception. Note: The comic below does not show material from ASM 654. The release date of ASM 654 was April 2011.
Inside the comic below we have two dates: May 2011 and 2/28/2011. I suspect that the May date was added due to expected convention release. The second date in the Indicia is the printing date of this work and makes it the first appearance of Flash as Venom and is his first cover appearance. This book previews issue one of the Venom series which debuted in May of 2011. This comic book was a con exclusive. All the other Marvel mix-tape comics indicate the con for which they will be distributed at. This book does not. After some research I have learned that this book was released at Wondercon 2011 at the start of April so even if this book had an April publication date it would likely still predate ASM 654 considering April 1 was a Friday.
Because this comic has a date of 2/28/2011 and thanks to its April distribution I see no reason that it should not be considered the first appearance/first cover appearance of Flash Venom. To date I have found no other book which predates this one.
