Veteran cartoonist Roger Langridge has issued a call for help in finding several pieces of original artwork that came up missing following a September exhibition in Italy. They were to be shipped to London, but apparently never arrived.

"I have no idea what might have happened to them," he writes on his blog. "I'm keen not to accuse anybody of anything, as I have no proof of any wrongdoing; there may have been a mistake made when packing the artwork, and it may still be in Italy. Somebody may have tampered with the package en route. I have no clue what the real story might be. What I do know is that I would like the work back. Some of the pieces are ones I intended to keep for the rest of my life. Others I was hoping to sell to help get me through a period where I'm not earning very much. One piece is the property of another person, who kindly lent it to me for the exhibition."

You can view some of the pieces here, and the rest on Langridge's blog (where you can also find his email address in case you've spotted any of this artwork).
