Note: owing to the paper used, very high grade copies without spine wrinkles and creases are hard to find! There was also a Press Kit available at the launch of the comic which was basically a cardboard lunchbox printed in the Crisis colours with an issue #1 and some character cut-outs. An example sold on eBay UK for £10.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
