W.M. Jigsaw puzzle #47 made by Walter Moberg of Colfax 2255 (possibly Benton Harbor, MI). Plywood, interlocking with 18 figure pieces. Classic WW I propaganda poster, totally unrealistic as troops coming ashore bunched up as shown would be massacred. My father served in WW I (and WW II as well) and told a very different story. Box includes lending library instructions re puzzle return, missing pieces, and assembly.
