From the Village of Cary weekly email,
The photo is of two decorative 6-1/4" advertising Dresden china plates from the early 1900's.
The plates are signed by the artist. The plates were from M.J. Skokan's store at 44 Crystal Street. Martin J. Skokan was the Village shoemaker.
The plates read "Compliments of Martin J. Skokan, Cary Station, IL."
All the above information and the photo, was provided by the Village of Cary, via their weekly email.
