Both sides shown...

I have:

170 yellow
166 brown
28 black
26 white

I have followed leads all over the place, and no one has ever been able to nail down where they came from.

I have followed leads to : Galveston, TX / Herrin, IL / Black Hawk, CO / Kalispell, MT / Nashville, TN / Oregon / Whitefish, MT. No luck.
