We ordered some advance Cow shirts to bring to San Diego and - erk! They have the wrong image! Our original version had the cow holding up a book entitled "Cud - a love story". Several (female) people told us that was a little gross and so we softened it to the final "Clover - a love story". Unfortunately our printer didn't get the message, to the tune of 144 (otherwise very attractive) shirts.
This isn't ideal, because we can't use the shirts we don't sell down there to fulfill the preorders we've gotten, but nor is it a disaster. The Comic Con crowd is probably edgy enough to appreciate the crassness, let alone the collector's value of a good misprint. Hopefully we'll sell them all, and live to tell the story to our granchildren.
