Lärobok i schack för nybörjare
Lärobok i schack för nybörjare is a Swedish chess textbook for beginners by Ludvig Collijn, published in Stockholm by F. Englunds förlag in 1920, third edition. The three pictures are numbered chess diagrams on a plain board grid, showing endgame and middlegame positions with black and white pieces drawn in sharp outline and hatched dark squares, a clear method for designers to borrow for checkerboard or game-board graphics.
