The handful I have for sale include some interesting ones. There's the HUGE Seaside Cove (honestly, the biggest rubber stamp I think I've seen).
It's about 27cm long! Read the manufacturer's description of this, though - they explain that you use parts of it to create the effect you want. Nice.
I think this one, Palms with Huts, is only available from Stampscapes these days in a smaller size. This is the bigger size - it would have been purchased some years ago.
And if this taste gets you hooked, the distributor of Stampscapes in Australia is The Stamp Trap.
So if you want to bid on my lot of Stampscapes stamps, here's the link.
