This sign advertised the envelopes sold in 1999 to commemorate 75 years of the American Motorcycling Association. It includes at the top of the sign a sent 75th Anniversay envelope, of which only 1000 were made. It measures roughly 18"x22".

This is a great collectable that could be displayed in your home, garage or office. And for some of you, there may not be a difference between the three.
