Comment on Ozone Layer Day by alexmax
I like this...this is cool! May I borrow for use as a background image on my handmade greeting cards? I have SR-71s and other planes and ships that this would go with...
I guess it depends. If I had done this for myself, I wouldn't have a problem. Since this was done for someone else (an advertising agency) it belongs to them. If it's something you are going to use in non-profit material, like it seems to be the case, it is probably fine.
