Vintage Gumball machine vendors association decal

Description

Another item  pulled from my dad's stash; THREE new old stock water slide decals to advertise that the operator is a member of the National Vendors Association. These are water slide decals. They are about 1 1/4 inch at the widest part. I guess the were put on various gumball machine, peanut machine, candy vending machine, trade stimulator or slot machine. Have got to be at least 30 years old, does anyone know if this association is still in business? Will add an 'aura' of authenticity to your machine. Look to be in very nice shape, were stored in a cool dry basement, so I expect they will work, BUT, no guarantees.
