This collection consists of class materials, objects, photographs, and printed material either salvaged or donated by various individuals. The class materials include teacher's master copies of worksheets, student evaluations, and students' notes. The objects consist of 4 autograph albums donated by former students, an artwork, and two drawers filled with student report cards. The photographs mostly consist of class photographs, in black and white, although there are a few in color. These photos range in date from the early 1920s-1984. Printed material includes books and booklets used by teachers in the classroom, plus journals, brochures, and newsletters used by teachers as supplemental material. Unfortunately, many of the digitized materials in PastPerfect are missing, such as student evaluations and color photographs from a class field trip. It is also unclear who owned some of the photographs in the albums and whether or not they depict PS 23 in their entirety. MOCA held an exhibition in 1991 called, "What Did You Learn in School Today? PS 23, 1893-1976," which brought in many of the class photographs and autograph albums. In addition, MOCA organized reunions for graduates of PS 23, which also drew many visitors and photograph donations.
