Kathleen Hamilton was a British Columbia potter known for making small hand built bottles and flasks like the ones shown here. A graduate of the V.S.A., she cites Kay Dodd and Barbara Baanders as influences. Occasionally you will see impressed paw prints in the clay, apparently from her pet cat.
This is Kathleen Hamilton's chop mark. If you have a piece of her pottery (or many) you would like to part with, please feel free to contact me here.
