[BRZESZCZE, mine]. Geological profile through the "Andrzeja" shafts. Lithograph on sheet 65.2x182.5 cm.
The cross-section of the mine was drawn up by Mieczyslaw Romanowski in 1920, the "Andrzeja" shafts were managed by Z. Lebiedzki (the likenesses of their signatures appear in the lower left corner). The plan was made at a scale of 1:1,000. The Brzeszcze coal mine in Upper Silesia was founded in 1903, and is still in operation. Traces of folding, rubbing on bends, browning of part of the sheet on the back, trace of dampness.
