Talk into any American Heritage Federal Credit Union office in the Philadelphia area, and you'll quickly realize what the phrase "American Heritage" in its name means.

Every branch has five or six historical documents posted on a heritage wall. An item may be a document signed by John Quincy Adams or George Washington, a letter from Herbert Hoover, a piece of china Eleanor Roosevelt used in the White House, an original "I Love Lucy" script signed by Lucille Ball or Martin Luther King's autograph.

Documents like these rotate from office to office every four months so members coming in see something new. Even if you're using P.A.T., the personal automated teller with two-way interaction to a human representative, the logo on the machine is a man in Colonial-era costume.
