An under-rated title as a sort of poor man's Look & Learn, worth it alone for the Wrath of the Gods strip with art by John Burns. Wonderful! Free gift with issue #1 Pathfinder Watch Compass in its original brown packet is pretty hard to find. Managed to get one years ago. Courtesy of Mr. Malcolm Phillips' great auctions. Adds maybe £50-£70 to the value in my opinion.
There were no Summer Specials and the annuals 1964-1972 are pretty common, maybe apart from the first one. The 1971 annual is stuffed full of good artwork including a Don Lawrence Trigan Empire lookalike comic strip. Check it out for yourself.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
