He wrote honestly about a profession he worked at all levels. His travel/food programmes sampled the fanciest of foods as well as the greasy spoons, local cuisines, and all without arrogance or false humility. He was very relatable for many people.

I would recommend reading Kitchen Confidential. Alternatively watch any of his travel shows although I think understanding the man through the book first makes it easier to appreciate the shows.

Regarding this specific find I don't see anything particularly special but for many it's one final glimpse into the life of someone they admire.

His really early ones were kind of rough. Like you could see he was still figuring it out. There was one episode where he just narrated a lonely planet guide.
