The earliest directory I have is for 1965
. It lists that membership as belonging to Leslie Rupert of Seattle, Washington. The Big numbers are made from a flexible plastic sheeting and will be issued you by the club when you pay your membership. The decals usually start to degrade and lose their red color after about 6 years in the northern climate and 3 years in the south. You can buy another set from headquarters every ten years if you want to keep up appearances. The Airstream aluminum plate can be lightly polished and then painted carefully a medium blue to improve its looks. I do not know what color the aluminum dealer was originally.
