"...I congratulate you for your initiative to direct a book on sketching and design to the students of art, architecture and planning...Therefore I am happy to participate to the publication by sending you two pictures of sketches belonging to two different projects of mine, both very famous." - Alberto Sartois.

"...The architect cannot face architecture as an isolated thing, that in opposite, now-a-days everything is interlaced, and the ideal is not only to know how to draw but to be interested in plastic arts, literature, and everything necessary for his behaviour in this unfair world we live in." - Oscar Niemeyer. Architect, Brazil
