This is a drawing of architectural gallery plans. The image shows two sections labeled as Gallery No.6 and Gallery No.7. The structure features large, rounded archways with intricate detailing above them, and walls framed by horizontal lines. Gallery No.6 includes various sculptural elements such as statues on pedestals, one within a niche in the wall, and another standing freely. Notes about materials like travertine, plaster, and marble are written on the left side of the drawing, giving additional context to the architectural style. The perspective is a precise, linear drawing, potentially a site plan or blueprint, dated May 6, 1939, and references the name Donatello.
