Timely, thanks for the explanation. I'd still like to know how the Grand Comic Database reached that conclusion. If you look at the four jungle themed covers on Adventure 36 - 39, they all appear to have been drawn by the same artist. However, none of them are signed, which is an anomoly if they are Flessel covers. Every other cover that Flessel did, including his Sandman covers, is signed. In addition, as I mentioned in my earlier post, the style of drawing seems a little bit different from Flessel's style. If anyone else knows anything else about this, I would be interested to hear it.
