Unmarked Creamer(?) w/Indian head

OK, so I do not know alot about pottery or the like, but I knew I had never seen a piece like this with a Hand Painted Native American Indian head painted on it. On the back it has a BROKEN wagon wheel painted.. and what COULD possibly be some sort of signature, starting with an 'M' , or it could just be the way the artist painted the wirey straw grass below the wheel! The specimins i've seen before all have Flowers painted on them, or perhaps a victorian style painting of a small child.. Anyway, I like it, but would really like to know more about it!! ANY help would be fab!!
