I've always thought that postage stamps are a great go-with for collectors especially when they commemorate insulator/electronic related topics.

This lot consists of the following cachets in a range of disciplines from telegraph to sound recording:

(2) Different cachets commemorating the 100th anniversary (centenary) of International Telecommunications Union, established in 1865 (2) Different cachets commemorating the centenary of the completion of the first Atlantic Telegraph Cable (1) Cachet commemorating Alexander Graham Bell as an inventor (issued in 1940) (1) Cachet commemorating the centennial of the invention of the telephone (1) Cachet commemorating the centennial of the first public use of the telegraph (issued 1944) (1) Cachet commemorating space based communications (1960) (1) Cachet commemorating the centennial of Edison's sound recording invention (1977) (1) Cachet commemorating progress in electronics including microphone, radio tube, TV tube, and radio speaker (1973)

The entire lot can be yours for 15.00 post paid.
