You will find a similarly formed group in my book, People, Passions, Pastimes, and Pleasures: Staffordshire Figures 1810-1835. That group was photographed from the collection of the Fitzwilliam Museum, Cambridge, UK.
A word of caution. I have seen double-deer spills made in such a way that the deer can be lifted off the base. In other words, each deer was potted separately from the rest of the figure form and then put into position at the end of the manufacturing process. This makes perfect sense, if you think about it. This large group was vulnerable in the kiln and if a deer was damaged, you lost the whole thing. But if you made the deer separately, you could replace a damaged deer with a perfect example.
