From the Vignelli Center Archive blog:
JG Furniture Co., Inc. was located in Quakertown, Pennsylvania and closed its doors in 1998 after nearly 70 years in business. Vignelli Associates designed these brochures for the company possibly around 1974.
The large type is set in Permanent Headline, with smaller supporting text set in what looks like ATF Garamond or similar.
Some of the photography for brochures is credited to the Swiss-born graphic designer and photographer, Herbert Matter.
