Today's (Wednesday's) Wall Street Journal has an article on Mickey Mantle cards, particularly the 1952 Topps, in its sports section (on the back page of the Personal Journal section). It's also online, but behind a paywall, and I'm not sure how to provide a link that will work for non-subscribers. Below I've put the link that they give to e-mail the article, but I don't know if that will work. In any case, I took a picture of the article and posted that below, and I think that should be legible.
