Note: While hanging out with David at the Summit, he shot Bud Riley at work (?)
This Turnbull photo was a suggestion by Bud Riley...Bud appears in the far left telephone booth.
David Turnbull was a contributor to many professional photography magazines and was considered both an excellent writer and photographer. Excerpts that follow are several pages from the 1988 Economic Summit that was held in Toronto.   
The following excerpt of the October 1984 issue of Photo Life features a Halloween article by David Turnbull, providing photographic tricks & treats. The boys in the photos are Bud Riley's sons Shea and Ryan who loved
the opportunity to mug for David's camera​. They especially had fun applying fake warts on their faces
