Gold Employee Lapel Pin

From Keystone Telephone Co. - Employee lapel pin.


Keystone Pay Station Sign

c. 1900's - Porcelain coated steel sign would identify the location of a public payphone. Measures approx 8 1/4" X 8 1/4". Usually the sign was displayed to inform the public of a payphone located nearby or attached to the telephone booth. These signs are very difficult to find in any condition.

c. unknown - This ring has the same logo as the Gold Employee Lapel Pin (below) displaying 1 center keystone surrounded by 3 smaller keystones. On the ring there are three stones, what look like a clear stone and two red stones, one set in each of the smaller surrounding keystones. This ring would fit either a person with very small fingers or possibly a child.

c. 1902 - An interesting little ribbon pin with a medal and bakelite telephone receiver. Likely offered as a token to be worn by Keystone representatives at the 6th Independent Telephone Convention in Philadelphia.

Interesting that 1902 was the year Keystone of Phila started doing business. Amazing condition for being 117 years old.

Keystone Telephone Co. of Philadelphia Intercom

Closeup of Front-Click Here Side View of Intercom-Click Here

c. 1910's - Measures 8 7/8" X 6 5/8" - Not only is this Intercom interesting because it is marked Keystone, but additionally it is part of an intercom system with the novel feature of being able to receive calls from outside the premises, and to put them on Hold. I have no idea who manufactured it and am not able to open without damaging the instruction paper.
