Transportes del Norte Bus Line Vintage Playing Card Dominoes

I can't get enough of these old domino playing cards, which I'm discovering were produced in some variety including many as free give aways, such as these from Transportes del Norte, a bus line running from Monterrey in Nuevo Leon, Mexico, to Loredo, Texas. These have a nice weight and gloss coating, and are a bit unusual in featuring both dots and numbers both. Plus that great black and blue bus graphic on the backs!

Complete set of double sixes, in very good shape, with some wear to the box but still holding together well. 2 5/8" x 1 5/8.
