A six-panel fold-out brochure from Audio-Technica, September 1980. The centre spread lays out twelve phono cartridges with photos and prices: three toroidal VM models AT25/AT24/AT23 led by the AT25 at ¥39,000, the paratroidal E/G series from AT150E/G down to AT120E/G, two VM-with-headshell models AT110E/H and AT105/H at ¥9,000 and ¥6,000, and the MC block AT34/AT32/AT30E/G headed by the AT34 at ¥38,000 with a dual moving-coil system. The inner page and the cut-away page lay out the VM idea: the cartridge body mirrors the shape of the record-cutting head; cross-sections of the AT25, AT150E/G and AT34 sit next to the cutter-head diagram itself. The back page carries the specs table and the “other main AT products” column: tonearm AT1100, microphone AT813, stereo headphones pointS, accessory AT6012.
