On closer inspection, the article is more about music and musicians - Coldplay and Radiohead's Thom Yorke, bringing new albums out on cassette and advertising them in quaint old-fashioned ways, such as small ads in local papers, or personally-typed postcards to fans delivered in the good old post.
But there's no reason to stop there. There are so many ways to advertise your brand or cause in real life, from posters to trams to vans to blimps - even on bricks and mortar.
I did learn a new word from the article that I'll have to use somewhere soon: anemoia - nostalgia for a time you've never known.
In the meantime, let's market like it's 1899!
