Traveling blackjack game in Oregon is correct, and the chips were used in at least 2 locations, perhaps more. Oregon has a weird statute that allows for "floating" BJ & poker games, as long as the local jurisdiction approves. Lots and lots of gaming history in that state. Don, these "match play" chips with the oxen and wagon come in $1, $2.50 & $5.00 and are rarer than the regular issue chips.
