This is Dave Hoover at his absolute best. It is a vintage piece as evidenced by his signature being inside the ovaloid. Pieces like this are the reason "Hoover" is one of my favorite search words on Ebay. I really lucked out getting this one.
There is at least one other collector who believes he has the original of this one. My guess is that Dave Hoover made one or more prints of this. I examined mine under a magnifying glass. Without the glass I can see that my image is on the back of a commercial comic book board, complete with blue lines, labels and the like. In mine, the halftones have their dark parts following the grain of the paper with the high parts being dark and the valleys being uninked, something that wouldn't happen with a print. Furthermore, the other alleged original is signed in big letters and dated in the blank area below BC's legs, an unnecessary act if it was the original since it is already signed in the lower right.
