So, I follow a page on Facebook called Shellback Artworks which is an art supply store run by Steve Lavigne, long time TMNT colourist for Mirage and TMNT Licensing Art. Occasionally Peter Laird, who he is still close with, comes into Shellback Artworks and sometimes he does some sketch covers for Steve to colour and sell.
Steve posted two up on his page the other day and I was quick enough to snag the second one after missing out on the first.
Steve coloured them both with the red Mirage bandanna, so technically it could be any turtle. But since my favourite is Raph anyway, I figured that to me it will be Raph haha!
