Brand: Excel Sound Corporation
The Excel Sound Corporation ES-75 QSL SS is a Commemorative QSL card issued by Excel Sound Corporation in honor of the legendary 94.5 FM New York radio station WBLS-FM, which first signed on the airwaves in 1967. The card features the ES-75 logo, the WBLS-FM call sign, and the phrase "Community Conscious Radio" on the front. Additionally, the backside includes a QSL message, space to record the contact details of the communicating parties, and a brief history of the radio station's founding and heritage. The card's "SS" designation denotes it as a commemorative card, which intentionally lacks an SINPO rating utilized by standard QSL cards to designate the signal strength and stability of the transmitted signals.
