The page features a dark background with an illustration of a vault door on the left side. The text of the document is presented on the right, overlaying the dark background. The heading "THE BLACK VAULT" is prominently displayed in a stylized font at the top. Below the heading, the text explains that the document was obtained from an online database of declassified government documents, specifically mentioning the "MKULTRA/Mind Control Collection" housed by The Black Vault. A URL is provided at the bottom for accessing the collection. There are no photographs, handwritten annotations, signatures, official stamps, forms, diagrams, tables, redactions, or visual evidence of experimental procedures present on this page.
The document is a typed "Office Memorandum" from the United States Government, dated December 3, 1952. Handwritten annotations include "A/B, 2: 22/9" near the date, and "H-B/3", "F", and "B/3" in the left margin. There are visible redactions (blacked-out areas) obscuring text within paragraphs 4 and 5, specifically in relation to specific groups or services and potentially personnel names. The document appears to be a standard memo format with clear sections for "TO", "FROM", and a "SUBJECT" line. No photographs, diagrams, or tables are present.
