Photograph of Norm Tully, Douglas Burke, and Herb Larson learning how to use the new Speech Indicator, a "tactile communication" device developed by Hugh Moore of the Los Angeles City Schools. In this picture Tully and Larson speak with each other on the phone using the device while Burke looks on. The device was designed to "provide a deaf person with a visual signal by which he can identify various telephone signals and code replies." Tully, Burke, and Larson were all long-time advocates on behalf of the deaf and hard of hearing. (Quoted from the Speech Indicator Manual). Black and white photograph, 5 x 7 in.
