Vintage Autodex Art Deco style Flip-up address book • Brown with black marbled plastic • possibly Bakelite but untested. The holder isn’t marked in an area I can see since the back has a cover. The last page gives the model name as ‘Pacemaker’. It also has directions for use and information about repairs. The address for Zephyr American Corporation is pre-zip code which indicates this is an older model. Nice vintage Preowned condition with a few scuffs along the bottom edge, stains on the backing, paint loss on the letters, discoloration on the bar and slide pieces. Measures approximately 7-1/2” x 5”. The sliding mechanism and bar work well. Pages are filled. SEE PHOTOS.
