Folder containing bundles of workings and figures for seven hypotheses for ‘Kugelsternhaufen’ (trans. globular clusters), presumably created by Becker.
Front page of first and second hypotheses says ‘Grundlagen für die III-VII Hyp. nicht zu viröffentlichen’ (trans. groundwork for hypotheses 3-7 not for publication)
Also includes loose workings/figures at back of folder.
