*Marvel: Many folks say – with justification – that Felicia Hardy, the Black Cat, was a Suspiciously Similar Substitute for DC’s Catwoman, created to give Spider-Man a ‘beloved enemy’ vibe and increase the romantic tension in the series. Probably true; but nevertheless, the Black Cat rapidly stepped away from her derivative roots, primarily owing to her low level probability manipulation – subconsciously causing ‘bad luck’ for people who opposed her – and the fact that although she’s frequently done heroic and noble things, she’s never completely shed her criminal ways. These copies of the Black Cat’s debut in Amazing Spider-Man #194 & #195 come from the non-distributed ‘wilderness years’, so there are no pence variants of these issues.  
IN THIS UPDATE: AMAZING SPIDER-MAN
#194 VG+ £150 (PICTURED) A nice copy, with tight, firm staples, spine ticks and some handling wear, decent off-white pages; it is marred by a colour-breaking crease of 11 cm across the bottom right corner.
#195 VG- £20 Spine creasing and minor impact damage at the base of the spine, plus more wear than is normally seen on this issue, although the staples and pages are good.
