The chess set shown here can be assigned to the Austrian Upright type. It is almost identical to the pieces used in the 1910 World Championship, in which Emanuel Lasker defended his title against his challenger Carl Schlechter. The original set of the world championship match is now kept by the Lasker Society in Berlin. It differs from the set shown here essentially in the shape of the knights. The 1910 knights were of a somewhat higher and slimmer, stylised form, while the knights used here are more massive and more reminiscent of the knights used in Viennese coffee house games. Many assume that Lasker-Schlechter type sets all match the 1910 pieces, but this assumption is wrong. There were several versions of this set with different knights. According to Michael Ehn, sets such as the one shown here were mainly produced in the period between the outbreak of the First World War and the early 1920s.

The king size is 11 cm. There are sometimes slight differences between the individual pieces, both stylistically and in size. It is not entirely clear whether this is due to tolerances and deviations in manufacture or whether pieces from different upright sets were mixed together here. Regardless of the latter, this is an extremely rare and valuable find, which some collectors would consider a "holy grail" set.
