Mini Rolodex Brass Plated Pocket Sized Pop Up Address/Phone Book - Vintage

This address book is in good used condition. There is a little rust on the slider button and in a few other places. There is a little corrosion on the inside on the metal. All of this is visible in the pictures, please see the pictures for specific details. I did not see any writing inside the book, and the slider works. This address book is miniature and measures approximately 2 1/2" x 1 3/4" x 1/4".
