Printed in 1989, The Baseball Card Variation Book Vol.II covers variations from 1948 through 1989. Yearly updates were made available through 1997 to include more baseball card finds plus basketball, football, hockey and some non-sport variations.
Arranged by producer and year, the book is a checklist of variations with brief descriptions of the differences between the known versions.
At the time of its printing, it was by far the most comprehensive listing of variations ever produced. The original comb-bound manual is 60 pages. The yearly additions increased the page total to over 220 pages.
The book plus Xeroxed copies of the yearly updates are only available directly from the author.
