So, a number of years ago I did a trade with someone on a local vBulletin style forum. In fact it's been so long that I can't recall the full details, but I'm almost certain that I thought of it as a cracking deal at the time, which has fueled my current paranoia. Anyway, what I received was Alfred and Killer Croc minifigs from Batman I.
Recently something quite inocuous happened - on the same forum I noticed the same guy saying he had Alfred for trade. It struck me as low odds that someone would have a second Alfred lying around having traded one to me already, and I started to wonder. I remembered also that he once mentioned having Decool minifigs in his collection, and the paranoid meter went up to 11.
Anyway, I took the minifigs out and I've taken some pictures, hoping someone here can confirm I'm being paranoid. Any help appreciated.
Here are the pics of Alfred. I was initially worried that I didn't recognise that style of head, which Killer Croc shares, but my Batman I Two-Face (which I believe is legit - bought on BL from seller with pedigree) has the same style. As you can see below, there is a 'LEGO' stamped on the top part of the legs, but it is in a different position from where it's printed on Croc's legs (Alfred's is vertical, Croc's is horizontal). The LEGO logo is also on both minifigure necks, though the camera wasn't able to focus well enough to show it properly on Alfred. There is no LEGO stamp on the inside of the legs at the base, but judging from some of my old minifigures this may just be something that is done on newer ones.
Here's Killer Croc (apart from his head, which I seem to have forgotten to take a picture of):
