Yup. the Gorilla is almost 6 feet tall and about 3 feet wide.That's a LOT of sparkplugs!
I would say it's a plug.sculpture?
I used to do the same when surf fishing.When I was younger, I used to ocean fish from the shore and used old spark plugs for weights. Don't think I used quite that many though!
I think it was to advertise the opening of a new store.doesn't it seem odd someone commissioned (actually paid for) this sculpture?
