Joe's picture from Dawson Creek (186K)
This picture was taken in May of 1983. A number of notable plates are visible, both Alaskan and other plates.
The Alaskan plate highlights include a couple of heavy-truck plates (silver on black, "Mx" prefix), some passenger and personalized plates from the '60s and '70s, and some commercial trailer plates.
If anyone is interested, I can send them the original TIFF (better resolution).
Alaska license plates are manufactured by Irwin-Hodson Metal Manufacturing Inc., located in Portland, Oregon.
