[ALR-bishop]

I have done the set plus an unopened pack. I have not undertaken the monumental task that Ted has with the very tough gray back series. I do have the red and black backs ( and the front differences in some of the first series cards related to those different backs) , and all the Sain and Page variations.

I also have the Campos black star, and the unlisted Campos variation with the missing upper left front border which was discussed in a recent SCD article.

I also have both variations of the Mantle, Robinson and Thompson cards, which involves the reversed stitching on the baseball on the back...left or right ( the Mantle also has significant front variations). The last 3 are not formally cataloged as far as I know, but fairly well recognized. I also have 3 fairly distinct front versions of the Boone card ( 2 simply related to the red v black back situation).

I do not have the color background difference for Crandall ( orange versus red, if it exists), but do have the two different color fronts for Feller. There are apparently several front background color variations out there that may be more fading or sunlight results than actual printing differences

Ted---based on my experience, your near completion of the gray backs is an amazing accomplishment

Jim---when I finished all the Topps sets, my "compulsion" took over. Be careful :-)
