This photo was taken by Tony Triolo (1930–2006), not Arthur Rickerby. I think it’s good to learn the differences, to see how Tony’s early images were more about the action, for example, while Arthur focused on the individuals. Plus, Arthur took too few photos of the New York Rangers, and Rickerby Hockey wants Ranger fans to feel welcome as well.
In defence of any shortcomings you might note in Tony’s photo, know that it was shot in 1966 when the technology was in its infancy. See that series of spotlights hanging off the wall? Sports photographers of that era were learning to assemble their own strobe systems, so I’m wondering if that’s what that is.
