My husband won't let me collect side saddles so instead I collect antique photographs of women in riding habits, horses in side saddles or females riding side saddle.
Out of my collection, I would probably say this is the most unusual. The photo (a cabinet card) dates to the mid- late 1880's and is of a young woman sitting on her side saddle on a wooden stand. This photo was most likely taken for an artist to use when painting a portrait of the young lady.
I love her saddle, it looks new and just look at the little off-side horn and the little purse too! She has a typical 1880's habit with a tight fitting bodice although on the photograph itself (not so evident on the scan), you are able to see where the photographer took off some of her waistline (this was done on the negative with pencil before they printed the photo).
