Next door to the Hall of Presidents is Heritage House, which sells Americana -- such as parchment-like reproductions of famous documents, historical campaign buttons and heritage flags. Run by the Historical Research Center, they can help you with your family crest or coat-of-arms

There are also several vendors and carts nearby, including the open-air Liberty Square Portrait Gallery, where you can have your portrait done, the Silhouette Cart, where artists create and frame silhouette drawings of their subjects, and the Umbrella Cart, a spot to get personalized parasols.
