Parker Bros may have been aiming at a younger market (as compared to trains, ships, etc) with this puzzle. The lithography is beautiful and stills shows even though I have not cleaned the grime off of the puzzles. The nail holes indicate that this is another stack-cut puzzle set. This style of cut and type of puzzle set was produced at least through the 1920s; dating puzzles similar to this without a box is difficult. I think that this particular puzzle really does belong in the pre-1900 category.
