I like it with a few minor quibbles.
The old footage is great, but would be even better with a caption e.g. Woolworths Grafton Street c.1983
And a bit more context to the changing of the times for those not old enough to remember the actual events...
As in, they showed an ad for Maurice Pratt drinking 'yellow pack' beers and it was much later in the episode that they (in passing) explained that they were the first own brand products.
And the bread price wars, what was the price of bread before and during the price wars.
