Here's your bogey - the stamped version has no other label, the labeled version has no stamp. Both came from the same dealer, both genuine GM, should have bought about 50 of them when they were this inexpensive.
You can see the location for the stamp, plus the color and relative size and font. Like Joe says, ought to be a piece of cake to have a stamp made for it at an office supply store, or online. Good luck -
