Cottees Auctioneers in Wareham held one of their Poole Pottery sales yesterday. I was bidding online and won just one of the dozen or so lots I tried for. The four spice jars above were the first of my lots to come up, and although I lost these, I now wish I had tried a bit harder to win them. It's just hard bidding twice the estimate for pots with so much damage to them.
I have my own set of jars here
http://robspoolepotterycollection.blogspot.co.uk/2011/02/early-storage-jars.html and V&A have their lone Pepper and Currents jars, but I had no idea that Peppercorn, Ginger, Mixed Spice and Nutmeg ever existed until I saw these pot listed in the sale. So at least, now I know there are more jars out there to complete my collection, and very possibly more than the four shown here. I just need to keep a look out over the next few decades waiting for them to come my way.
