I usually participate in a couple of national level philatelic exhibits featuring parts of my collection of postal librariana each year. On Friday my philatelic exhibit on Presidential Libraries and Museums will go on display at the American Philatelic Society's AmeriStamp Expo 2010 in Riverside, California. The show runs February 19-21 at the Riverside Convention Center. The exhibit consists of six frames of 16 pages each featuring the presidential libraries and museums administered by the National Archives and Records Administration. It is entered in the Display Division which allows some non-philatelic material to be included in the exhibit. In addition to many special event and first day covers related to the libraries and museums in the exhibit, there are library dedication programs and invitations to special events. Signatures of Presidents Truman, Ford, Carter, and Clinton on items in the exhibit are included. I first showed the exhibit on a non-competitive basis as a three frame exhibit at the American Philatelic Society's show in Grand Rapids, Michigan in 2005 where one of the first day of issues ceremonies for the presidential libraries stamp took place. The Riverside show will be the first time the exhibit has been shown competitively at the national level. I also have a three frame non-competitive exhibit at the Riverside show featuring America's Philatelic Libraries and Museums. If you live in the area stop by. Admission is free. There are many other exceptional philatelic exhibits on display as well as a large number of stamp dealers.
