Here is another recent JunkWaxGems article I wrote (includes links to a few others who've covered the topic previously) on the topic of edited/airbrushed cards. I've long been attracted to the Fleer Randy Johnson varieties and I fondly recall sorting through tons of junk wax 20+ years ago hoping to find others. Over the years I've slowly found other examples though none to the degree of effort that Fleer made that year.

If you have other examples, please share, I'd love to continue building this entry with as much of them as possible (credited to you, of course). I'm currently keeping it at 1977 through 1995 but not inflexible about that.
