I found these two mounted tintypes in an online auction and loved the fact that they are clearly mother & daughter AND that the subjects are in the exact same pose. They even have matching embossed stars on the border around the photos.
I asked some very knowledgeable friends of mine about the coat that Mother is wearing, in the first image above. They tend to agree it is a garment called a sacque coat, meaning any sort of coat that buttons at the neck and is loosely hanging on the body. It ends around the waist or hip line. This particular specimen has trimmings around the hem and very large buttons that appear to be decorative rather than functional. A pocket is also evident, with something tucked inside. Perhaps it was a handkerchief or small book. The coat was probably made from wool or wool flannel, and lined with polished cotton or silk. I say “probably” because even though we don’t see the actual details of the garment, these are the most common materials for outerwear at that time. I bet it was very warm and comfortable! We don’t see much detail about her dress, except that it has a small collar and she is wearing a lovely brooch.
Second in line is the daughter, who has a bolero style over bodice with a white Garibaldi style bodice under it. This was a very popular style for young people. The over bodice is similar to the sacque coat in that it fastens at the neck and hangs loosely around the body. You can also see her large belt buckle. The dress was probably made from a fine wool, and the over bodice was likely lined with polished cotton in a solid brown or black (the most common lining in extant garments). The Garibaldi bodice was possibly made from fine cotton lawn, sheer wool or silk, depending on the family’s financial situation.
Neither card has a backmark, so I cannot tell anything about the photographer or geographic location where the tin type images were made. Each tin type is approximately 1 1/4″ by 1 1/2″, and is affixed to the mount with a sheet of thin paper glued over it. The mother’s card was trimmed down, presumably to fit into a frame or photo album. They are lovely representations of the American Civil War era or slightly thereafter, definitely pre-1870s.
