1968 Topps Information

I'm a few years too young to remember this test issue.  I also don't know if it was even available in my area.  I've been going to card shows since 1976 and I don't ever remember seeing these cards.

Here's a link to Keith Olbermann's article about the 1968 Kellogg's test issue and its variations.
