At the height of Marshall Studios in the 1950s and '60s, husband and wife team Gordon Martz and Jane Marshall were turning out 1000 handmade lamps a week. The couple met in college studying ceramics, and after graduation settled in Jane's home town of Veedersburg, Indiana to take over Jane's family's lamp business. Both skilled potters, the couple handmade original design lamps, pottery, tiles, and eventually furniture. The pieces were made by slip-casting, ram pressing, or jiggering, and everything was hand decorated.
In the 1980s and '90s, the mid century modern aesthetic was less popular, but today a pair of Marshall Studios lamps in good condition can run over a thousand dollars, and select pieces are on display at the Museum of Modern Art in New York.
Above, I've rounded up seven Marshall Studios pieces currently for sale on Etsy: (clockwise from top left) M77 Cruet, No. 191 Lamp, Walnut Lamp, Tea Cups, Pitcher, Pottery Set, Ceramic and Teak Lamp.
