I think it's great that other Joe fans are enjoying this picture as much as I enjoyed making it. This was a blast to create. I'll try and keep posting more artwork, and I'll be sure to add in the missing Joes from this piece within the week. And I'll definitely move forward with the Cobra poster. Thanks for the interest, guys!
As for purchasing this? I really didn't think of that going in, and I'm not sure I can legally sell it since the piece is all about copyrighted characters. I have no problem with anyone right-clicking and saving the image, as long as YOU don't go selling it, either! I do have some 8.5x14 prints left from the convention. Maybe we could work something out where you reimburse me just for postage if you want a print.
Let me think on it, work out some details, and update when I have more info.
Thanks again to Mr. Hama for his kind words and for posting my picture to his FB page, and thanks to you guys for the positive push forward.
