From the USPS press release: ”We are proud to celebrate the enduring impact of Fred Rogers and Mister Rogers’ Neighborhood with this new stamp from the United States Postal Service,” said Siefken. “Fred Rogers left an indelible mark on generations of young audiences through his groundbreaking series, and his timeless wisdom and important messages of inclusion and neighborliness remain just as relevant today as they were 50 years ago.”

I watched the USPS First Day of Issue Ceremony live. Walt Seng, who is a friend of mine, is the photographer/artist whose photo of Mr. Fred Rogers holding King Friday XIII is the basis for the stamp that was dedicated. I was expecting to see Walt up on the stage as part of the ceremony and receiving some of the honor. But, he was not included in the filmed ceremony. Why did the Postal Service neglect having him up there? Walt has a bit of a story to tell about the photo and much more to say about his work photographing Mr. Fred Rogers back in the day and should have up on the stage sharing in the honor.
