|An Aldo Cherini drawing?|
Don't know where the above is from.
|From Chapter 3 of Return to the Islands|
|From an old National Geographic|
The photo above is, I believe, a photocopy I made from an old National Geographic magazine - I wish I could remember what island it's from!
|For reference only - a canoe from Kiribati|
I will say this, however, regarding derivation. IMHO derivation takes place all the time in all manner of art and science. From yacht design, to cooking, to learning by imitation. It's more a matter of development...
One must, of course, give credit where credit is due...
