Thirteen of the first 32 books in the series had clearly marked reprints. Then only two in the next 124. It is difficult to believe that the first 32 books were so much more popular than the final 124. Export may have had trouble in the first months establishing adequate print runs. Or they just stopped marking reprints. It is a little suspicious that the final two books with marked reprints are so close together - 122 and 124. At any rate here is the first NSL reprint.
The first reprint is one of the first two unnumbered books in the series, Mark it With a Stone by George Victor Martin. The first printing is undated. The second printing states "First News Stand Library Edition May, 1948 | Second Printing, June, 1948" on the copyright page. The second printing is 8mm wider and has a red stripe down the right side of the front cover and left side of the back cover and a yellow overprinting of the blurb at the top of the front cover. On the back cover – “MARK IT WITH A STONE | GEORGE VICTOR MARTIN” and “Acclaimed … BARE” are in red vs. blue on the first printing.
