This photo is from around 1984ish when a lot of the Westport area was being pulled down. The ad was actually on the side of the former premises of Young's in South Tay Street, where the new buildings on the corner of Cross Lane now are. That means at the time I was taking the photo I would have been standing at the gap next to Slickers, looking over towards Marketgait.
John Young was still there in 1970 , and were present at this location for quite a few decades up to then. Looking at the phone number, I'd say the building ad is probably from around the 1930's period.
