My grandfather served in the "Phantom" GHQ Liaison Regiment. Among his souvenirs are two publications called "PUM" (a monthly journal "for the Ps by the Ps", giving its offices as the Regiment's HQ in Richmond) and "Phantasia". I have been unable to find any record or mention of these journals elsewhere online and would appreciate any further information about them.
I wonder whether my dad did that illustration? I know that there were a number of artists drawing for Phantom publications, but the style looks familiar. What do you think?
