Me too, I spent a lot of time on these. Good thing I like doing these cause as you know it doesn't pay. The sketches don't seem to be selling well, They were all listed very high last week, most are being relisted for 99 cent starting bids.
I think Topps missed the boat on this one. The parody doesn't really appeal to the baseball card collector, and the fact that these aren't actual products doesn't really appeal to the Wacky Packages Collector.
Nice job on the sketches, by the way!
Since you don't know if they're approved or not, is seeing them on eBay the only real way to know that they were produced? If so, that must be an elation/downer for you. An elation that it was selected and cool to see it in print, but also a downer that the person who got it was willing to put it up on eBay rather than keep it. I know that a lot of collectors buy cases, open them up, keep one set, and sell the rest to pay for what they keep. If they love sketches, they'll keep 'em, and if their goal is to make a profit, then it's off to eBay with 'em.
Hope you get more work on Wackys.
