<Li> 1942: A special emergency series, with brown serial numbers and "HAWAII" overprinted on both the front and the back, is issued . These notes are designed to circulate on the islands and be deemed invalid in the event of a Japanese invasion . </Li> <Li> 1948: The White House picture was updated to reflect renovations to the building itself, including the addition of the Truman Balcony, as well as the passage of time . Most notably, the trees are larger . </Li> <Li> 1950: Design elements like the serial numbers are reduced in size and moved around subtly, presumably for aesthetic reasons . </Li> <Li> 1963: "Will Pay To The Bearer On Demand" is removed from the front of the bill below the portrait, and the legal tender designation is shortened to "This note is legal tender for all debts, public and private" (eliminating "and is redeemable in lawful money at the United States Treasury, or at any Federal Reserve Bank .") Also, "In God We Trust" is added above the White House on the reverse . These two acts (one taking U.S. currency off the silver backing, and the other authorizing the national motto) are coincidental, even if their combined result is implemented in one redesign . Also, several design elements are rearranged, less perceptibly than the change in 1950, mostly to make room for the slightly rearranged obligations . </Li>
