thanks for the Townsend link David. I only have four tiles and these came from a charity shop some year or two back, and I've compared my tiles with images on your link, and whilst three are identical, there is one - the Seal - which differs from the image shown on your link.
Your picture shows a seal reclinging on its back, whilst my tile depicts the animal sitting upright facing right - very different. If you'd like a pic. of this different pose let me know sometime
