I found this photograph at my Link page Northern California Bus Fans, which is located to the right of your computer screen at www.norcalbusfans.com ( A really cool photo page.)
The General Motors Corporation had introduced their "New Look" models of TDH Series Fishbowl Windshield buses in 1959, and they were an instant hit. Many city transit agencies owned and operated these during the 1960's, 70's and 80's, and the city of Dallas Texas was no exception.
Dallas Transit GM fishbowl windshield transit bus # 93, is viewed passing through downtown Dallas Texas, way back in June of 1980. According to this, Dallas Transit at one time had painted their city transit buses in this very unique and colorful paint scheme back in the day. Nice.
