Last reported slot card from the Sunray Park & Casino in Farmington, NM was a blue card with "Come Play With Us" with four race horses across the front. That card had no manufacturer's mark but an identical card was just reported with an (I) mark on the reverse.

Scans of both cards are on the ChipGuide now along with all the previous issues
