USPS Roy Lichtenstein Forever Stamps Sheet of 20

Got a full sheet of the Roy Lichtenstein Forever stamps here. It's a cool set of 20 stamps featuring five of his different pop art designs like 'Standing Explosion' and 'Modern Painting I'. The sheet has a photo of the artist himself on the left side. Great for any art lover or if you just want your mail to look way better than everyone elses. It's in good shape, no folds or anything through the stamps themselves.
