A few decades before producing their now iconic Color Cubes, the U.S. Embossing Co, of Albany, NY, made these, in 1907 specifically, as is indicated on one block reading "Erected 1907," meant to serve as a cornerstone of sorts. I believe this is actually a few sets merged together, making a fantastic big lot poised for erecting all sorts of structures,  in most cases with blocks featuring different patterns on each side (some of the green and white square ones are the same on both sides.) Included are blocks of several different shapes featuring brick patterns, as well as ones showing doors, steps, lights, clocks, and windows, And though I think they once came in branded cardboard boxes, whoever owned these consolidated most into a big beautiful old wooden finger jointed slide top box, with the overflow in a smaller un-lidded wooden box of a similar ilk. Really a nice bunch.

Square, brick pattern blocks measure 1 3/4" x 1 3/4" x 3/4". All blocks are 3/4" deep. Large box measures 8 1/2" x 12" x 3 1/2" and is completely filled with them. Smaller box  is 8 3/8" x 4 1/8" x 2 3/8" and almost all of the way full. All blocks are in very good antique condition, with many many years of play left in them. They're great for stacking but also nice for arranging just laid flat on a tabletop.
