Purgatory Post celebrates 50th anniversary of Earth Day
As we close in on the end of this work week, I have one more philatelic item to share with you. The latest release from New Hampshire’s Purgatory Post, a souvenir sheet commemorating the 50th anniversary of Earth Day, was issued on May 4.
As is typically the case with Purgatory Post’s souvenir sheets, this sheet includes four stamps, in this case a 4-sola Earth Day design that I personally like more than the official USPS issue commemorating the same anniversary.
More out of the ordinary is the inclusion of two labels, one of which pictures United States Senator, Wisconsin Governor, and Earth Day founder Gaylord Nelson (1916–2005), and the second of which pictures Swedish environmentalist Greta Thunberg. Neither of the labels bears a demonination.
