Steve - that's about right. As Al explained to me he got them from the "Currency Exchange" i.e. places that you got yr check cashed in the Chicago area. These stores would also double as proxy for dept. of motor vehicle where you could get your new plates. These samples would be displayed on the wall behind the counter to show what the new (each year they changed) colors were.
BTW, Al worked at Nickey Chevrolet for a few years in the parts dept.
