A monthly series. Printed in France rather bizarrely.
There was a first series of sorts that began in 1944 or 11945 published by L Miller. An un-numbered first issue followed by numbers v#33, #37 and #50. I have never seen them for sale so can't really give any values. Just tough to find of course and valued at whatever someone wants to pay for them!
The monthly 2nd Series began in 1950 at issue #50 (#1).
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
