This is Kodak’s classic Master Darkroom Dataguide from 1958, the pocketable reference that lived beside enlargers for decades. It packs exposure indexes, developer times, paper grades, and toners into easy color-coded charts.
1.Better yet, both rotating “computers”—for film development and enlarging exposure—are intact and turn smoothly. Photo-verified, complete, and ready for a working darkroom or a design-forward shelf.

While I do my best to capture colors accurately, your monitor or device screen may display colors slightly differently from the actual item.
