There was one on eBay a while back - might have been the same seller as the Hankin "Howzat" - I think he was looking for $3000.
Tell him "your dreamin"
From memory - and I stand to be corrected - he had a "Howzat" and "Superman". Seperate auctions - I think he was from country Vic - out Gippsland way - Leongatha ? Can't recall. I do remember the "Howzat" was initially listed at around $3000. Now that I think of it - he might have sold it for $1500.
