The image measures apx 3x3 with the card slightly larger - the card has the typical slight curve of the era. These are in amazingly nice condition for being over 100 years old - this one has several small white spots visible in the 1st photo - very little discoloration or fading so I assume they were stored in a dark environment.
They look great in the square frames with the 3x3 openings - as shown in the third photo. NOTE: This listing is for the image shown alone - the framed picture is just for reference and may not be of the same image.
If you are interested is seeing the other images available before they are listed email me and I'll send samples and put up a custom listing for you.
