Thanks again guys. I think I can almost consider myself an expert on spotting fake cassette boards now. :chimp: Still unsure about labels though. Sometimes on ebay I see auctions listed as original casing and boards, but with fake label, even though the label displayed in my eyes looks exactly like the corresponding one on http://www.hardmvs.com/.
Did all original labels come with hologram/rainbow effect? What else could one look for?
