Hi Brian and All!
RE: Dugan Month
Today we would would like to share our collection of the Dugan beauty twigs vases. It has taken us some 30 years to collect our little beauty's. And must say we are grateful and fortunate to own them. Some years back, 2014 to be exact we were contacted by Dr. Larry Keig and asked if we would interested in sending him some information on our twigs vases as he wanted to do an article on the little beauty's. We were thrilled to share our vases with other collectors and with that we sent photos and measurements. Dr. Keig compiled a great article in the ICGA carnival pump newsletter vol. 49.1 September 2014 edition.
