1.75" bw real photo without dot pattern probably c. 1901 when she appeared at the Pan American Exposition in Buffalo. Her dress has 1/8" tan mark with a smaller spot at lower right and with several tiny tan dots on the upper scene but these are so small as to almost not show. Covered tin back stamped with name of maker "Pin-Lock" along with 1898 copyright. From the Hake collection and only example we've seen. Wonderful crisp details and super high gloss. Rare.
