Over the last few years I've undertaken the rather momentous challenge of collecting a complete set of WNYFs. I'm about two/ thirds of the way there, but any help would be appreciated. With that in mind I'm looking to buy or trade mainly 1940-early 1950s, mid 1990s, and 2007-2015 issues albeit I have a few holes besides those mentioned. I also have 40 duplicate issues that I'd love to find a good home for.
