I purchased this and several other vintage toys at an estate sale.  I have done some research on this bank and found that there aren't too many like this one, or at least I couldn't find many.  Well for one thing it was a pull toy.  You can see the little "hitch" were a string would have been attached to pull it.  The other thing is the car itself.  There are different styles of car the the wiener sits on but my research shows that this must have been one of the original cars.  I can't guarantee it but there aren't many of these with the words ALL MEAT WIENERS it is on both sides of the car.  I have found a picture from the 50's that shows the car with those words on the side.
