Shmuel Guttman was one of the last generation's great designers. His genius was not expressed in innovating new designs, or creating contemporary versions of ancient designs. Rather, his contribution as a great artist was in the minor modifications of small details of popular designs of others which he created.
For example, when Odetta sang a song written by Bob Dylan, her talent as a singer, and her creative interpretation of the song, expresses her genius. The song remains written by Bob Dylan, but her creativity exudes from her version of song.
