The two horses hitched to this Omnibus (New York, c. 1900) must’ve been been awfully good boys. There seem to be some pieces missing from their harness, as they have neither saddles (the part that goes around the horse’s midsection, where a riding saddle would go) nor breeching (the part that goes around the horse’s hindquarters and that helps him stop the vehicle).

I’ve seen old photos of work harness without saddles, and it was not uncommon for pair and team harness to lack breeching. But I think this is the first photo I’ve seen with just collars and traces, and nothing else.
