Copyright has expired on the 'leghorn ' caricture. New paintings and art as such is a different mater. The picture is genaric enough to avoid trouble, besides,I dont think WB is typically roaming around my small farming town.Lol
Love your sign...I too want to come up with an idea for a sign to bring in the customers....
( altho, I am selling my eggs at the nursing home where I volunteer.... and I may not need a sign, if the staff keep buying up my eggs faster then my girls can lay them!! )
