Recently bought this off ebay.
To be honest, my current insanity led me to buy it simply because it had a photo of Hank in its accompanying leaflet that I hadn't seen before! I tried to play a couple of the cassettes, but they were a bit wonky after all these years! The set is quite nice to look at, but just for one photo it was a slightly mad purchase. Looks like the photo in question was probably taken in 1973 or 1974. Oh, and they've printed it the wrong way round! Anyway, here it is...
