Background:
Gwen Ifill was among the first African Americans to hold prominent positions in both broadcast and print journalism.
After graduating from college in 1977, Ifill worked at The Boston Herald American, The Baltimore Evening Sun, The Washington Post and The New York Times. In 1994, she took a broadcast job at NBC, where she covered politics in the DC bureau. Five years later, she joined PBS; she became the senior political correspondent for “The NewsHour with Jim Lehrer” and moderator and managing editor of “Washington Week” — the first woman and first African American to moderate a major television news-analysis show.
In 2013, she became co-anchor of the “PBS NewsHour,” part of the first all-female team to anchor a national nightly news program. Ifill died in 2016.
Among Ifill’s honors were the Radio Television Digital News Foundation’s Leonard Zeidenberg First Amendment Award (2006), Harvard’s Joan Shorenstein Center’s Goldsmith Career Award for Excellence in Journalism (2009) and induction into the National Association of Black Journalists Hall of Fame (2012). In 2015, she was awarded the Fourth Estate Award by the National Press Club. She received numerous honorary degrees and served on the boards of the News Literacy Project and the Committee to Protect Journalists, which renamed its Press Freedom Award in her honor.
The 2016 John Chancellor Award was posthumously awarded to Ifill by the Columbia Journalism School. In 2017, the Washington Press Club Foundation and the “PBS NewsHour” created a journalism fellowship named for Ifill. Her alma mater, Simmons University, opened the Gwen Ifill College of Media, Arts, and Humanities in 2018.

October 23rd: PBS has noted this stamp. The story is here.
Hopefully HQ will let us have a local ceremony at the Museum of African American Art in my hood eight blocks from my home. They love the Ries Chapter there and we have helped at a number of very successful events there over the past few years.
There are both First day of Issue, AND First Day of SALE postmarks. If not one, then the other. Talk to your Postmaster/District Manager. ( I know, preaching to the choir … )
Trust me, Lefty, Michael is very familiar with FDOS postmarks, alternate ceremonies and his local postal personnel. He often helps with cancelling at Southern California events.
Maybe they’ll film the show at the studios of WETA where Gwen Ifill worked… ( Maybe get a camera angle where you don’t see the back of the heads of all the old bald guys… )
As seen above, Not at WETA-TV.

Where: Metropolitan African Methodist Episcopal Church

In Post Bull 19 DEC USPS# 4758 On Auto-Distrib DCP, PIC, and ANY CITY cancels.
As of 01 March, the Ceremony Memento 475834 is SOLD OUT!
As the Stamp, and both the PIC & DCP are still available for sale,
I have Inquired with The Caves if USPS will have one of it’s printers produce some more of these. At $24.95, this would bring more CA$H for a poorly funded Postal System. Once they run out of Stamps, that’s another story…
USPS had a ‘Stocking error’. The Ceremony Memento for Gwen Ifill, and all of the other current issues ( except Maine ) are again on sale, and available on USPS.COM.
Two questions on Gwen Ifill issue
Are stamp pins made anymore thought I saw one during the tv coverage about the stamp.
If so how do I purchase one?
How do I get a special deadication issue for this?
I believe they are. I will check. Usually, they’re handed out for free at the ceremonies, and then sometimes given away at the big stamp shows.
Ok thanks
USPS National Events does produce stamp pins for free distribution to attendees at first day ceremonies. They are not for sale.
Ceremony programs will be available for sale shortly in the online USPS Postal Store and the USPS eBay store.
