Consists primarily of work Geck created during his studies at the New York School of Fine and Applied Art and renderings from his years as an instructor for the school. Life drawing sketches appear to have been completed for a class Geck took during the spring 1923 semester, possibly under the instruction of Harry Baker. Watercolor renderings include costumes, furniture, textiles, interiors, and stage designs. Some renderings indicate Geck based them on items he saw at the Metropolitan Museum of Art and Museum of Natural History in New York, while others were created at historical sites he visited with students in Europe. Seven sketchbooks, organized geographically and then chronologically by Geck, contain measured drawings of interiors in England, France, and Italy. One oversize folder contains large pen and ink renderings of identified French and Italian interiors as well as two hand-drawn maps of Italy executed while Geck was teaching at University of Colorado at Boulder. Arrangement is alphabetical.
