This is an event cover for 85th anniversary of Superman's first appearance in Action Comics #1 in 1938. It is postmarked on June 1, 2023 because Action Comics #1 had a cover date of June 1938, although it was released sometime in April or May. Cover is hand cancelled in Toronto; Joe Shuster, the artist and co-creator of Superman, was born and lived in Toronto as a child. Clark Kent's newspaper, originally called The Daily Star, was inspired by the Toronto Daily Star. 

The cachet is laserprinted on a hand-folded envelope made of high-quality bond linen paper. This cover is numbered 13 out of a limited edition of 15.
