Court documents show that 4.9 billion stamps were printed with Davidson's work. According to the documents, the Postal Service collected more than $4 billion in revenue from stamps using Davidson's statue. Before the stamps were retired total revenue was more than $70 million.
BBC reported that, according to the documents, USPS was made aware that the stamps used an image of Davidson's statue in 2011, but still sold the stamps.
“The government points to the fact that the Postal Service did not notice the difference between the two faces itself until notified months after producing many millions of stamps,” the court opinion said. “The conclusion for defendant is that nothing original must have been copied. This is nonsense.”
The Postal Service told CNN it is "reviewing the decision and will comment if and when appropriate."
In 2015, a federal appeals court upheld a $540,000 judgement against the Postal Service when a New England artist did not give permission for his sculpture to appear on a Korean War stamp.
