Great piece of research by Malcolm Philips. Commando at War was a 30 page booklet given away with Adventure #1551 dated 9th Oct 1954. Featuring details of commando skills and weaponry, he postulates that this could have been the prototype for Commando Picture Library beginning in 1961. A VFN copy was sold from his Sep 2009 catalogue for £66.
