Clay Beastie, Lovable Critter~Signed, but is it Devin?

Hello All,
I'm home today after a few uncomfortable medical tests,...feeling fine.
Sitting around watching old time Westerns on the TV,( love the old ones ), I decided to whisk myself up into the attic to see if I could find a few worthy posts.
This curious but lovable beast has been part of the family for a few years.
He has yet to be displayed in the house, but not for lack of love,( the house is PACKED!)
He's about 8 1/2 inches high, 12 3/4 inches long and signed what looks like ' Devin ', but I'm not sure.
(I'd love someone to tell me that 'Devin ' is a name that Lisa Larson used:).
It wasn't the effects of anesthesia that brought him in front of the lens,...I think he's adorable.
Maybe someone knows more about him, or his maker?
Thank You.
