The latest Trivia Almanac illustration hurdle–I’m looking for versions of the White House portraits of U.S. presidents.  The ones I’ve found on-line, at whitehouse.org and whitehousemuseum.org, are too small for reproduction purposes.  (I had a roommate in college who was also too small for reproduction purposes.)

Does anyone know offhand where to find larger versions of White House portraits?  Have they been published anywhere?
