If you spend any time at all around Pennsylvania and 15th you know that tourists love to take pictures of the Treasury Building there on the corner. It’s a little funny because it’s just offices, and even the statue on the Penn Ave side is of a guy few have ever heard of save perhaps some economics and NYU wonks. (For the record, it’s Albert Gallatin, the fourth Secretary of the Treasury.) Yet the architecture, symmetry and scale make it the perfect quintessential “Washington” building, so you can’t help but take a quick photo. I probably have a dozen photos hiding in my Aperture library, and this morning I couldn’t resist … so now there’s one more.
