Like Spectre Stories, John Spencer and Co Ltd were trying to emulate the success of Alan Class type comics but these rather third rate artwork offerings never really took off. Hard to find but little collector interest unless you are a completist! I have only ever seen the 5 issues though a 6th is rumoured to exist.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
