[amsat-bb] Grid Square Maps

Back in my county-hunting days I had purchased, from somewhere, a poster size black on white map of the continental USA with all counties shown. As each county was confirmed I could "color in" that county with a felt-tip marker. So I could quickly see if I needed a county heard on the air.

Is anyone aware of a similar commercially available map for the USA that shows grid squares which could be colored in as they were confirmed? How about for Europe or other areas?

Thanks. Tom, KØTW
