Digest (pocketsized). European reprints in black and white.
A run of #1-16, #18 and #19 came up for sale on eBayUK in Nov 2016 and fetched £103. First time I have seen these for sale so tough to find. Interesting that other guides say only 17 issues were published.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
