TMNT VOL.4 #30 w Sketch..es

I was able to get one of those limited edition TMNT #30 with a sketch from Peter Laird, actually I got one that includes a sketch of all four Mirage Artist. I think I read on Peter's blog that there was only 5 of these made. How lucky am I?? I'm digging the comic and sketches. Thanks Mirage team for taking all the extra time to make the sketches on the comic books.
