Rochester Philatelic Association Larry Rausch purchased a pane of the new U.S. Dragons stamps at APS StampShow/ATA National Topical Stamp Show, and put one on a postcard before noticing something was amiss: 
The clerk wanted the sheet back, but Larry tells The Virtual Stamp Club he wouldn’t part with it. The other 15 stamps are still on the backing sheet.
Because the last row of the sheet has no perforations, Scott catalogue editors who have seen the sheet say it is “unperforated,” not “misperforated.”
At last report, veteran EFO collector John Hotchner now owns the sheet.
Did the clerk ask for the stamps back so they could make a profit by selling them to a dealer? Do they think stamp collectors are stupid? Larry purchased the stamps legitimately. They’re his!
I think that’s unfair to the clerk. They are supposed to prevent the sale of incorrectly produced stamps.
