Old Authentic AT&T stock certificate Bell telephone

Authentic engraved stock certificate from the American Telephone and Telegraph Company (AT&T) issued in late 1960s and early 70s. This is an original certificate, not a copy or reproduction.  I have brown (shown), orange or green versions of this certificate with the color being selected randomly. This certificate has an ornate border around it with a vignette featuring a portrait of Alexander Graham Bell, Inventor of the Telephone, a metropolitan city with a map of the world in the left background, and a large radio tower with a rural community and map of the world in the right background. It also has the company's corporate seal dated 1885 at the bottom center. The certificate offered is the same as the certificate pictured except for the date of issuance and registered owner.  NOTE: the certificate offered in this auction is what I consider a second grade certificate and accordingly has noticeable fold marks and/or pen marks, hence the lower price. However, if bidding equals or exceeds $12.00 I will automatically upgrade the certificate to one that is in excellent condition (no folds or tears but may have a stray pen mark).  The certificate is punch cancelled and has the normal punch cancellation, stray mark and staple holes. These are hard to find, historical and quite attractive. The telegraph and the telephone, both important breakthroughs in communication, were developed during the 19th century. With their introduction, people, for the first time in history, were able to communicate over long distances instantaneously. Alexander Graham Bell (1847-1922) was trying to improve the telegraph when he invented the telephone in 1876. A teacher of the deaf, Bell based his invention on the vibrations of the diaphragm in the human ear. Thousands of improvements were subsequently made by others, but Bell’s basic patent remains one of the most valuable ever issued by the U.S. patent office. By 1910, more than seven million telephones were in use in the United States. Please note that old stock certificates are becoming a hot collectible due not only to their historical significance but the fact that with the advent of electronic trading companies are not issuing shares in the quantities they did in the past. Accordingly, they are becoming harder to find and presumably more valuable. Please review my feedback and bid with confidence.
