Help with a price

I have a Flambro Emmitt Kelly Jr 70th birthday snowglobe I'm looking to part with. Could anyone help me with a price to looking for ? It's from 1994, shows the clown looking from the outside in, through a window in brick wall, into a bakery with cakes decorated for birthdays. The water globe rests on a birthday cake type base. It's really quite large. Stands about 7" tall and 6" wide.
I'd like to put it up for bids on ebay, but I have no idea what to expect it to go for. Any help would be very much appreicated from Emmitt Kelly Jr collectors such as yourselves !
Thank you for your time to read this !
