The Duke Tinted Photos set (ACC #N89) is made up of 50 cards showing unnamed actresses and was issued around 1887. The cards come in two versions – a regular, tobacco-sized card and a die-cut version, for a total of 100 cards. The images are the same in both versions.
These cards show colorized photos on the front with a Duke ad at the bottom. The die-cuts do not have the ad on the front. The backs have a generic Duke ad – the same on both the regular size and the die-cuts.
I haven’t found a formal checklist, the cards are unnumbered so it would just be a description of the image. I may go ahead and compile a list anyways and will update this post when I have the additional information.
