19814 📃
An A2 sheet folded in four, 8 pages - a booklet for a single model: Sharp GF-999 “Searcher W” at ¥123,000, August 1981. On the cover conductor Hiroyuki Iwaki listens to the boombox at his feet and remarks “well yes, it resonates nicely” - an unconventional ambassador choice even by Japanese standards. The entire booklet is built around two principles: three-way acoustics with a dedicated super woofer and separate amplifiers for each band, plus dual cassette for ping-pong dubbing and home multi-voice choir recording. The ¥123,000 price tag was at the top end of the portable equipment market in 1981.
