Probably J.D's best known pressing, and Registered on 3rd July 1874 - based apparently on one of Landseer's recumbent lions which can be seen in slightly bigger format in Trafalgar Sq., London - this one is a little smaller at about 7.1/4 x 5 inches.
Fully marked with the anchor/JD and a clear lozenge - there are examples in Ray Slack and Jenny Thompson - Slack shows a black example and Thompson's pair (courtesy of the V. & A.) look to have been in clear glass - don't think there's one Hajdamach - according to Ray Slack they were produced in frosted, clear and coloured glass. As with one or two other three dimensional pieces from Derbyshire, they were described in the factory's submission to the Board of Trade as paperweights - for this one the Register at TNA, Kew, reads ........... "Lion after Landseer for a paperweight".
Unfortunately, this one has a substantial crack, but since I probably couldn't afford one in v.g. condition, this is likely as near as I'm going to get.
