I recently scored an incredibly rare lot of a complete set of NOS playfield plastics for Rocky and Bullwinkle on ebay. These plastics were still wrapped in the original protective blue covering. I peeled each one and scanned them in at 600dpi, which gives all the microscopic detail you could possibly want. Enjoy!

Note that these are just raw scans. I've not attempted any clean-up of specks of dust or anything like that. Also most decals, cabinet art, and backglass art are not included, though I am working on scanning those in as well.
