I was put in touch with Jay by Jeff Shepherd and he was quite helpful when I was researching my book, The Modern Guide To Topps Chewing Gum: 1938-56. From what I have seen, he was like this with everybody. I'm slowly working on a Topps artists project and while I won't be able to hit him up for information, he will be a focal point nonetheless. I'm also sorry I didn't get a chance to get into longer discussions with him about Woody and folks like Len Brown and Ben Solomon. He was around the place for such a long time, through the IPO in 1972 and the ceding of control by the Shorin's later on, through the sale to Michael Eisner in 2007 and beyond.
His papers (which are voluminous) are being donated to Ohio State University. They include documents and artwork from his entire career; he apparently saved everything he could over his 72 years. Considering the circles he worked in, this will be a valuable resource to a number of disparate folks.
Topps has put out a commemorative set to help his family defray his medical expenses, it's available here if you are interested.
