Esselte Map Service (1913 - 2000), also known from 1962 as Esselte Kartor, was a Swedish cartographic publishing firm formed by the merger of several cartographic companies and lithographic printers, the largest of which was the Generalstabens litografiska anstalt (G.L.A.). The name Esselte was initially informal and later formalized, and comes from the pronunciation of the company's acronym S.L.T. (Sveriges litografiska tryckerier), though for most of the company's history its constituent firms continued to use their own names. In 1962, Esselte was reorganized and Esselte Kartor was created to handle all cartographic output. The company was known in the late 20th century for its atlases and massive wall maps, often produced in conjunction with governments and cartographers in non-European countries.
