Wm. F. Drueke & Sons manufactured hard wood games for most of the 20th century, beginning in 1914. They released dozens of cribbage board models; this item, the No. 1, was their most basic travel board. Extra small so that it fits easily in a coat pocket or travel bag, with peg storage underneath, and only about 7" long.
This is a clean, high-quality example, with a board that shows little to no wear, unmarred pegs, and the original box and instructions. See photos for details.
