I always find it disappointing when various models, signs, or, in this case, stamps choose to feature such rare examples of the car. For example, in 1967 there were 602 Z28 cars, but it seems like about 75% of the memorabilia featuring 67 Camaros is of the Z28. In 69, there were at least a lot more Z28s made, but still fewer than 10% of the build (so not super representative) ... plus, how many black 69 Z28s were there? ~100? So, yippee, there's a stamp for 100 potential owners out there!
Cool stamp and it's nice to see the Camaro in the bunch ... just wish it were a more representative trim and color.
