Expo 67 - Algerian Pavilion

This photo is starting to convince me that maybe some of my dad's Expo 67 photos weren't taken in 1967 at all. Combing through Dad's negatives can be a frustrating experience. Some are recorded meticulously; others are the proverbial negatives in a box.
 The white building in front is the Algerian pavilion. The green things that look like abstract trees is the Canadian Pulp and Paper Industry Pavilion, standing in front of the green Toblerone-shaped Steel Pavilion. However, our crack research team (me and Google) has found evidence that the Steel Pavilion had signs along its apex that spelled out "STEEL" in 1967, signs that are noticeably absent in this photo. So perhaps some of his pictures, particularly the colour ones, date from the years after 1967, when the site was run as an exhibition called Man and His World.

You can see the STEEL signs above the pavilion in this photo he took in 1967 (and probably taken from a monorail).
