Those vertical pin striped horse collars must have been the height of fashion in the equestrian world at that time.

As a dedicated fan of vintage photos I do believe that is the first time I have ever seen "fashionable" collars and also the first time I've seen any collars in mint condition

rather tacky.

I recognize the tops of lawnmower handles.

That was the "old" lawnmower we owned, which was all around impossible to push through grass. A newer one we got later was possible but no fun.

Today's push mowers are very easy to push, but they cheat, geometrically rising over hard to cut grass and leaving a clump, instead of stopping and locking up the wheels there.

I use a scythe today on my acre of lawn. (No kidding)

Maybe there are old pics of the Palace of Versailles showing how it's done.
