Earlier in the thread, in response to a request, I posted an image (and my alteration thereof) of Neill Sheridan. The image came from a licensed set of San Francisco Seals cards done in an old timey style. The guy responsible for that set (Carl Aldana) released a new set of Seals just a couple of months ago...this one in the style of Mother's Cookies. I swear I'm not his publicist; I just really dig the cards and wish I could afford them (they aren't prohibitively expensive; I'm just flat broke). Fortunately, the eBay seller offers them as sets and as individual cards (the latter of which means good sized scans).
So it's still Seals and I've no doubt its colorized (and, sure, the screen is not as fine as you'd like). But I still think--
all factors considered, it's probably the best Sheridan I've seen.
