The National Postal Museum has on display the first public appearance in three decades of the legendary Benjamin K. Miller Collection, which is known as the “crown jewels” of U.S. stamp collecting. The Miller collection is so large that it had to be exhibited in two parts. The stamps that are now on display at the museum are from the years between 1894 and the mid-1920s. The museum previously had Miller’s stamps from before 1894 on display, but switched to the 1894 to mid-1920's stamps on October 1.
Uh, the Miller Collection will be on display only until January 12, so, uh, you might want to go there and see it some time. I was there when the exhibit opened on October 1, and I've been going back to the museum about every other weekend to look at the stamps.
