I just got back from vacation and saw this thread on the Cosmic Rainbows. I agree that they were done after G-V (1982) and before Anacortes. I use the 45+1 count bags for reference here since I don't find 45+1 prior to the G-V use. Here's a Vitro Bag - Flag Label - Parkersburg with All Reds and some of the 'Lilacs' - (kind of dates them maybe also); then another Parkersburg flag label bag with cat's-eyes, including a green glass shooter; then the 45+1 flag label bag of Cosmic Rainbows (again Parkersburg); then a similar style bag with the Paris Manufacturing info printed under the Parkersburg line (by the way, some of the Paris bags were glued - no staples); then I threw in the flag label style bag with Anacortes in place of Parkersburg on the info line (that's a 50 count bag). So, they did print some headers on the Parkersburg style before they switched to their well known silver label.
