Unfortunately, it's not a complete set... So come on, all you posties and ex-posties who read what's on libcom - I'm sure some of you must be able to provide the missing documents! This collection just goes up to #11. There were supposedly 13 issues.
I'm grateful to the 56a archive for letting me borrow and scan these copies.
