Black & White, CQ Magazine full-page print advertisement from March 1959 for GONSET'S SSB TRANSMITTER GSB-100 and SSB LINEAR AMPLIFIER GSB-101.

Excellent condition, with no tears, creases or stains. Lite foxing around the edges. Please ignore any cross-hatch pattern that may be on the photo, it is not on the ad, I may have had my scanner resolution too high for the paper type.

Securely packaged.
