Amazingly, my original copy remains in very good shape. Some years ago I also found a nicely bound second copy, in even better condition. So - sorted !
Somewhat superseded by the second book (+ Thacker, Nicholson and co. ) which came out later on though, although I still refer to the earlier book quite a bit.
The most annoying thing about it in the mid 70s was that the US issues they quoted were long since unobtainable in the UK (if ever they ever were outside of e.g. Dobells for about 1 day) , so that many of the titles remained elusive until the CD era.
Anyway - back to Hank...
