Neat old paper item that has 2 pages listed full of phone types from 1878 to 1965 plus a Bell System advertisement. Each Photo is accompanied by description of the phone type and features that were available at the time period. Both pages are no rips, tears, stains, or fades excellent condition and will be a wonderful addition to insulator and other phone related collections. I suspect that these pages are from the 1965-66' time period. $15 + shipping.
