What are the plate and sheet dimensions, and does a plate mark survive on any edge?

Dimensions are how a census row is matched, and a figure whose convention is unstated cannot be compared with anything. The working record gives approximately 137 × 104 mm without saying whether that is the plate or the sheet, while also describing the sheet as roughly trimmed. The Rijksmuseum records 134 × 103 mm for its impression. A surviving plate mark on any edge also tells you how much of the original sheet is left, which bears on what evidence has been lost.

Working record: approximately 137 × 104 mm, convention unstated, described as approximate. Rijksmuseum RP-P-1961-989: 134 × 103 mm. Bonhams 2022 lot (a different impression): sheet 125 × 103 mm, trimmed by 9 mm at the top and along the lower plate mark.

• The 137 × 104 mm figure is a sheet measurement including a margin beyond the plate mark on the untrimmed edges.

  Possible

  Would be internally consistent: trimmed on one edge, margin retained on others.

• The figure was transcribed from a description of a different object.

1. 01Measure under a conservation protocol, recording plate mark and sheet separately, to the millimetre, stating the convention and the measuring instrument.
2. 02Record which edges retain a plate mark and which are cut, edge by edge.
3. 03Photograph with a scale bar in frame so the measurement is checkable from the image.

A measured record made during the conservator visit, with the convention stated.

• RQ-01Does this impression carry the signature “Rembrandt f. 1638”, and if not, why not?
• RQ-07Does the verso carry collector marks, dealer codes or inscriptions?
