@ddreisba Yes, here is the address:
Citizens' Stamp Advisory Committee
475 L'Enfant Plaza SW, Room 3300
Washington, DC 20260-3501
You can read more about their guidelines and process here:
https://about.usps.com/who-we-are/csac/process.htmFunnily enough, the person who prompted me to learn about this and start this thread (Mister Fred Rogers) will be honored with a stamp next March! So while my original mission has been fulfilled, I enjoy reading about the other people/causes/events the rest of you bring to my attention. Thanks for sharing your ideas here (and I hope you submit them to the committee).
