John Naka "Bonsai Techniques"

Do anyone here know if there's any substantial difference between "Bonsai Techniques I" cover color maroon/red and "Bonsai Techniques" cover color green?.. just wondering..





edit: I guess the green book its missing the roman "I" but what else could be different on it?

usually it's a indication of edition. check on the first couple of pages and see the printing dates. the first edition was printed in 1973 and I think the cover was blue.

Other than the cover there is no substantial difference.

My GUESS would be that BT predates the release of BT 2, then was changed to BT 1 to reflect the new addition...

I think you're right Russell.
