I volunteer at a non-profit thrift shop which benefits animal rescue. Someone donated an unusual Hull planter that I need help with. I've checked many sites on-line and have checked a few reference books but haven't come across one like this. Unfortunately I don't have a Hull book, but I'm hoping someone out there does. This planter consists of 3 rounded pots, all joined together. Largest pot is 4" wide & 4" in height. The 2 smaller pots are approx. 3" wide & 3" high. The two smaller pots are joined to the largest pot on their sides, but the 2 smaller pots do not touch each other. The 3 pots are open on the insides where they join. Colors on all 3 identical - orange on the top halves and dark green on the bottom halves. Bottom of largest pot says Hull, and bottom of one of the small pots says 10T(?), possibly 107(?) I would greatly appreciate learning more about this piece (esp. value) so I can properly price it. Since all profits go toward animal rescue and assisting with low-cost spay/neuter to reduce pet over-population, I want to price it appropriately and not undervalue it for the animals' sake. Thanks!
