1-24 December: The Mayor Gallery, London exhibits "Calder: Mobiles and Stabiles." Calder's jewelry is also for sale. (CF, exhibition file)

11 December: A review of the exhibition at the Mayor Gallery notes: Calder's jewelry is as pretty as his mobiles--some of it too is "mobile"--and often more seriously lovely. If the lady of fashion has wit to see it, she may find that pieces of human ingenuity make rather more distinguished ornaments than Cartier's portable currency. (CF, exhibition file; "Alexander Calder at the Mayor Gallery," New Statesman and Nation, 11 December 1937)

14 December: "The show is going quite well.... Sold 3 objects so far, and a lot of jewellry." Buyers of his jewelry include prominent characters of London society, including Lady Clark, wife of London's National Gallery director, and Kenneth Clark, who had also puchased Calder's jewelry the previous year. (CF, Calder to Sweeney, 14 December 1937; CF, exhibition file, unsigned newspaper clipping from Sketch, 8 December 1937)

22 December: An unsigned review of the Mayor Gallery in British Vogue declares: Calder...occasionally makes jewellery [sic] of great charm and originality. He bends and twists gold and silver metal into fantastic and gorgeous patterns, very much in the modern manner. Women of taste should ask to see some at the Gallery. (CF, exhibition file; anon., "Shop-Hound Goes to a Party")

After 1 March: Calder is commissioned by Wallace Harrison and Andre Fouilhoux, architects of Consolidated Edison's pavilion at the 1939 New York World's Fair, to design a "water ballet" for the building's fountain. Although water jets are installed around the pavilion, this ballet is never executed. (Calder 1966, 176)
