The first such exclusive was, as I already mentioned, released some time ago in 2005. Packed in a special commemorative box, this included Minifigures of Batman and the Joker and a sound chip with a recording of the Joker's maniacal laughter and an announcement concerning the upcoming release of Lego Batman. This item was limited to only 250 and was available at the San Diego Comic Con, you would be lucky to find one now for any less than £100.
In 2006 a Lego comic book entitled Batman: Secret Files & Origins, was released, which contained a short comic strip showing Batman in action against his foes. This exclusive is the least expensive of the lot and costs only about £5 to purchase online as it is by far the most common.
Then, in 2008, a similar set to the initial 2005 item was released, with the same Batman and Joker Minifigures, but entirely new packaging and no sound chip or accessories for the figures. This time it heralded the release of the Lego Batman video game, which of course went on to be very popular. This exclusive is a little more affordable than the earlier edition, but still will set you back a cool £50 at least.
In my next post I will conclude my discussion of the Lego DC Super Heroes exclusives released over the years with the most recent of them, from 2011 and 2012. After that, I will return to bringing you updates on my Arkham Asylum MOC and the progress I have been making concerning the design side of things over the last few days.
