I guess that's the only location mentioned in the front matter of the first edition, so they wrongly assumed that London was the place of publication rather than Chicago. I'm not lucky enough to own the first edition, but I suppose it didn't implicitly state the location of the publisher because the facsimiles don't. Maybe it was published in London, then shipped over to Chicago for distribution!
The typos do seem odd given that this is Sotheby's. However, there was a well-publicised coding error in the Tim Berners-Lee NFT that they sold recently for $5.4 million, so perhaps proofreading isn't their strong point!

P.S. I think I linked to a digital edition of TEATCT that I created to help me learn the material somewhere in this thread. Unfortunately, it is no longer available on my now-defunct blog, but I have recreated it using Google Docs:
bit.ly/teatct. Hopefully, this will help magicians who don't have enough money to buy Ricky Jay's copy!
