Manufactured in Waterbury, Connecticut in the early 1860s. These are an early form of plastic using a shellac and powdered carbon base. The material allowed for press molding the dominoes making manufacturing much faster then hand cutting each different tile.
Domino Size: 3/4" long by 7/8" wide.
The dominoes were packed in a leather case with snaps. They were perfect for the soldier going off to the Civil War to carry in his back pack. However most soldiers brought bone and wood type dominoes that they had at home.
The company mark on the snaps led to finding the information about these dominoes.
