There are two copies of the Folio Society edition of Moby-Dick in the collection and this is the description of the first aquisition:
Herman Melville: Moby Dick The Folio Society, London 1974, First Thus. 515pp. Very Good in decorative cloth boards. Wood engravings by Garrick Palmer. Seems to be a bit of discolouration to lower part of spine, possibly water damage (there is a mark on the corresponding part of the slip case), apart from this would be fine.
Captain Ahab is clearly deranged and given the way Garrick Palmer has chosen to render skin, he appears to have a tooth ache, no doubt causing more pain.
