Glen S. Miranker is a former Apple executive who has collected over 7,000 books, illustrations and letters related to Mr. Sherlock Holmes. He has whittled them down into the New York City exhibition “Sherlock Holmes in 221 Objects”, opening tomorrow at the Grolier Club in Manhattan. The show runs until 16th April 2022. A catalogue is currently available, which may interest some readers of Tentaclii.
