I am looking for the grafter of these trees:

I cut out the image immediately above from an old Civilization Magazine - this was from those days in which I would cut up my magazines (shocking!) and not even write down the pertinent citation information (bad librarian!).

I remember this from the magazine: these photographs are from a professional gardener's own backyard. His specialty was trees and he molded the above creations for his daughter. The process took years.

The other two images are from an HP ad from an old WIRED issue that used the illustrations in a mock gardening catalogue.

Civilization magazine isn't well indexed so I have been having difficulty finding the original article. Any additional information would be appreciated.
