JC, I'd estimate out of the 150 photos in my lots approximately 10% where not Type 1s. Sometimes however the other types are much cooler! Check out this Lajoie. First is the base image. The second is the image with the floating head (a clearer image) attached (note the glue marks on the first image). The third shows both and the fourth is a published example of FrankenLajoie. This was photoshop circa 1910. A fascinating look at the editing craft.
