This quick sketch is a refinement of a scheme first developed in 1966.11:57. In that drawing, a square panel appears above the aedicule of the choir wall, but that is eliminated here. The scheme is also represented by the Tavola Quinta among the finished presentation drawings now at Columbia University's Avery Library.
The putti, drawn with the paper turned 180 degrees, do not relate to any of the Lateran design schemes seen in the Morgan drawings, but they likely correspond to the angels with garlands and banderoles found in a number of related drawings at Columbia University's Avery Library; see also a related sketch of putti at the Staatliche Kunsthalle, Karlsruhe, inv. IX 5159-36-2-4. Another drawing at the Morgan, inv. 1966.11:110, was once joined to this sheet.
Numbered at lower edge, in graphite, "53".
Watermark: Fleur-de-lis inside double circle, monogram "CB" above, centered on chain line.
