Street vendors in Washington were hoping visitors would want to own a piece of history….actually, LOTS of pieces. Obama-related pins, banners, bobble head dolls, pint glasses, mouse pads and calendars were available on the streets of D.C. These collectibles are great mementos but most won't go up in price for at least 20 years.An autographed program, a ticket to an official function, a personal item that belonged to the political family will be collectible, but since the 1950s, mass-produced items like shirts, buttons, hats and plates, have sold for very low prices years later.A few of the strange souvenirs offered for sale this week: soap on a rope shaped like Obama's head (the Audacity of Soap), lip balm, printed toilet tissue, an Obama Mr. Potato Head, "4 Barack" hot sauce, several types of coffee, tea, and an energy drink sold with Obama's picture on the label.Heard on the street, "Celebrate Obama. Buy a magnet for your Momma!"Someone bought the pennant shown here in 1941 to commemorate Franklin D. Roosevelt's inauguration in 1941. It did go up in price when it sold recently at a Heritage auction for $54.Search for more prices of political collectibles on Kovels.com and in Kovels' Antiques and Collectibles Price Guide 2009.Ran on January 21, 2009.
