This is a collection of six different editions of the early baseball card hobby magazine/newsletter "The Ballcard Collector".  They are Issue numbers 52, 53, 55, 62 and 2 more which don't have edition numbers but I think are 54 and 63.  Some are dated 1970 and the last few may be 1971.  Some tape on some of the covers but the magazines seem to have all the pages.  Interesting early hobby content.
