I purchased this pitcher ( I think this is what it is ), for $1.50 and really purchased it because it had a Picasso look to it. It appears to be by Italian artist Giovanni DeSimone, who was a friend of Picasso and was trained by him. There is a number on the bottom of it that I am not sure if it's a date or item number. Can anyone tell me what the numbers mean and if there is any value to it? The measurements are 10" high and 24" around the base.
