We don't sell technical drawings except when they are incorporated into a drawing or a collage.

And for every project, because it takes years, you can see the early drawings and collages as just a simple, vague idea, and through the years and through the negotiations of getting the permit, you see that every detail is now clarified.

Because we do not sell photographs, we have no royalties on books, posters, postcards.

We tell them that we believe it will be beautiful because that is our specialty, we only create joy and beauty. We have never done a sad work. Through the drawings, we hope a majority will be able to visualize it.

It's very important to understand that we never do the same thing twice; each of our projects is unique. We'll never do another 'Gates.' Each project is a unique image. We do not know in advance how the work will look. I do preparatory drawings, but they are only projections of our vision.

Therefore, when we arrive in a place and talk to new people about a new image, it is very hard for them to visualize it. That's where the drawings are very important, because at least we can show a projection of what we believe it will look like.
