fransar sign made from an old "creeper"

My idea originally was to build a sign for the market from some scrap pallet wood I had.  But after hitting some garage sales last weekend...I found the perfect sign!  I didn't know what you call these until I just googled it, its a  "creeper." (old mechanic cart used to slide under the car)  The man I bought it from looked at me like I was crazy when I was so excited to have found it.  I took the pillow and casters off...sanded it down and hand painted the sign.  I liked the end result.
