This weathered negative envelope, its edges torn and mended with now-amber cellophane tape, once safeguarded a set of captured Japanese wartime photographic negatives. Handwritten inventory notes catalog its contents as 'Captured Jap. Number Codes' and related 8x10 negatives — remnants of intelligence-gathering work conducted in the China-Burma-India Theater during World War II. Though modest in appearance, such envelopes are themselves historical artifacts, preserving the handling and cataloging practices of Allied intelligence personnel who processed captured enemy imagery.
