OC 54/133 Copy of a letter from Otto Vrieslander to Alfred Einstein (DMV), dated February 15, 1927

Following Einstein’s determination to have the Urlinie graphs engraved, not hand-drawn, Vrieslander asks that the engraver pays particular attention to the shape of the large slurs, and suggests a meeting with the engraver to go over further problems. If the graphs were relegated to an appendix, they could be as wide as necessary, for sake of clarity.
