Need a little help on this one. A friend of mine gave me this to list on Ebay for him. He said it was a turn of the century melon ball football. As I was photographing it to list on Ebay I began to wonder how anyone could get their hand around this to throw a pass. Its huge. So I started looking at photos of melon balls and couldn't find any that look like this. There are no stampings or markings. It is rock hard and I cannot find a place to inflate it. So what is this? I won't list it unless I can describe it accurately. If not, I'll return it to my friend. Hopefully someone here can ID this thing. Thanks.
