Notes:
- The printing date is stated as just "October 1971" and there is no indication on if this is the first or later printing for the publisher. It's likely this is the first printing date as other Fawcett printings from $0.75 to $2.25 are all using a 1971 date.
- Printing year of 1975 from comparison of catalog # and price to other verified Fawcett editions
- The catalog # is stated as P2307 on the front cover and 449-02307-125 on the spine. The ISBN 0-449-02307-9 could be derived from this but that value was not found on Amazon nor via Google.
- Prior to verification this ISFDB record credited Paul Lehr as the cover artist. However, a cover artist credit nor signature could be located and so the source of this credit is unknown.
- The cover image is from the Amazon, Jan-2008
