An embarrassing mistake involving a Statue of Liberty stamp is coming back to haunt the US Postal Service.
The stamp design released in 2011 was not based on the statue in New York Harbour, as intended, but on a replica outside the New York-New York casino hotel in Las Vegas.
Now, the sculptor who made the Lady Liberty of the Las Vegas Strip is suing the government for copyright infringement.
Attorneys for Robert Davidson argue in a suit filed last week that the Sin City statue was more "fresh-faced" and "sultry" than the original.
They say these differences caused the Postal Service to prefer Davidson's statue.
The actual Statue of Liberty has appeared on more than 20 stamps.
