300 Arranged U.S. One Dollar Bills ( 29in x 42in [74cm x 107cm]). I can only imagine what the teller at the bank thought when I asked for 300 singles. Only 65 to go!
UPDATE: 10 of these bills were entered into the Where's George website and sent to my friend Phil. You can track them using their serial numbers: A71952100D, F79130190D, E93308768A, E65039934H, E06270752I, A61182676D, A26198175B, L84053716M, E21114490A, E22823252A
