The paper measures 378mm x 374 (min)mm.
The printed map measures 366mm x 357mm.
This is a clean unfoxed specimen, a good impression with just the feintest of offsetting visible, in original uncoloured state. Maps from this edition frequently suffer loss when bound into the books; in this case, whilst the paper has been trimmed near to the margin at the lower left edge, there is no loss (see the photos). The paper is a good weight and there are no rips/tears/holes or repairs; there is a small nick (with no loss) to the top right corner, well outside the printed area (see the photo). I would describe this as a good/very good specimen.
This is not a reproduction or modern reprint. The photographs show the condition. I recently sold another specimen of this map for a lower price, but that reflected it was not in as good condition.
