dueling banjo playing pigs

An illustration from my book, "The Free Pigs". I have been reading posts by other illustrators with the banjo-playing pigs theme. I thought I would get in on the fun and offer this.

You know, I am not well-informed about musical instruments. I realize that this singing pig by the moonlit marshmallow roast is playing  something that looks more like a guitar.
Here is a link to another illustrator and fellow blogger who has a better banjo drawing. I like her pigs too. http://paulabecker.com/blog/?tag=banjo-pig
