The first one is by an artist named Ellyn R. Accord. She was the artist who did one of the first two I posted. I tried again to find out more about her but details were 'sketchy'. </groan> The listing described this one as being in the 'pop art' batmania style of the 1960s. Whatever. It's pretty nice. And the cost was $6.50.
So this one I really like. It's by artist Dave Beaty who does some really awesome work. You can see more on his site. The cost was $8.50 which was a bargain compared to what he sells his other stuff for. He did cards for something I had no awareness of...Batman: The Legend trading card set by Cryptozoic Entertainment / DC Comics. Looks really sweet.
So these two had a total cost of $15 not including shipping. That brings me to $27.50 of my $75 target. Next week I'll have a couple more to post including one whose pedigree as a true 'sketch card' is currently under review.
