"1939 Batman comic sells for more than $1M – Sale sets new world record for amount of money paid for a comic book". Incredible comic book related headlines like these have a vast impact. All the big newspapers like The Observer and The New York Times print them on their front page and even some less relevant daylies notice and publish this kind of amazing news. Hence the feeling of hitting on a gold mine whenever you'll find a pile of yellowish looking comic books in your attic or – even worse – your cellar. A while ago we received a phone call from southern France from someone who just had experieced that and seemed rather unsure whether to keep his find or throw it out with the rest of the garbage. It seems funny that strongly aged paper alone is a factor for a lot of people to assume great value. They usually forget that this is a mere sing of very bad storage while the dollars start piling up in their eyes. Pling, Pling, Pling. Issues like Detective Comics #27 featuring Batman's first appearance are rather hard to come by. There may be 100–150 original copies left worldwide and finding one is like hitting on the literal needle in the haystack. And if it's in good condition – well, then the needle is golden with a diamond attached. Looking at the very unloving ways most people treat books, however, guess what are the chances of that? According to Heritage expert Sandoval "... your usual comic from that age is falling apart, dog-eared, moldy". So most of the really valuable stuff like Batmans 1st may even be restored by an expert before going into auction. Creators Bob Kane (artist) and Bill Finger (writer) who gave life to this new and very different superhero in the late 1930s had other concerns anyway. They wanted a new type of hero and so even Batman's origins differ immensely from those of his fellow crime fighters in the DC universe: Bruce Wayne/Batman is not just all about the good deeds. His motives are much simpler. Batman is about revenge. Plus: he has no superhuman powers at all. No cryptonide, no tingling spider senses – just pure muscle power for which he even had to work out. A human being with a birthday (April 7, 1915) and a nice family life – which falls apart when his parents are murdered during a mugging. Crime is the origin of Batman and his crusade against it. His symbol for fighting evil: THE BAT. This great epic tale about vigilante justice started out in May 1939 making Batman one of the most controversial superheroes in the DC universe, and like many of the other heroes created during that period he was going to write comic book history. He will offer us suspense for many years to come.
