For collectors who have outgrown baseball cards, the organizers of the Washington International Print Fair have made it easy to move into the big leagues with their pamphlet titled “P101: The ‘Prints-iples’ of Buying and Collecting Prints,” which gives a crash course in such topics as “Know Your Matrices” and “Master the Terminology”; now you can go from rube to cognoscente in just a few minutes before plunking down 40 grand for a Dürer or a Whistler. The fair also features workshops on how to preserve your booty, in addition to the 15,000-plus prints, drawings, watercolors, and maps on display and for sale. Go prestige shopping from 10 a.m.-6 p.m. today and 11 a.m.-5 p.m. tomorrow, with workshops starting an hour before opening each day, at the Rosslyn Westpark Hotel, 1900 N. Fort Meyer Dr., Arlington. $6. (202) 638-6008.CP
