Earlier in her career, Judy Collins was very fond of the D-18. In fact, she even played one at the open house for Martin’s new Sycamore Street factory when it opened in 1964. Eventually, her focus shifted toward Martin 12-string models, mostly the D12-35, and this model became the guitar she was most associated with. When Martin decided to honor Collins with her own signature edition models, it was both 6- and 12-string Style 35 Dreadnoughts they chose. This model was owned by Collins for nearly 40 years before Martin Guitar acquired it for their museum collection.
