We carry portraits around all the time: pocket-sized history lessons in the form of dollars and cents. The recent decision to put Harriet Tubman on the $20 bill has us thinking about who\u2019s on our money, and how they got there. This episode of the \u201cPortraits\u201d podcast, from the Smithsonian\u2019s National Portrait Gallery, takes a whirlwind tour of money of yore, featuring everything from piles of bunnies to George Washington\u2019s nipples. This episode will have you taking a closer look at the portraits you might be sitting on right now.
