The most interesting of these, from the description at least, strikes me as being the Sherlock Holmes Paper Dolls. Here is the product description:
"The dean of detectives is a master of disguise so his doll comes with 10 different costumes. This set also includes 5 colleagues and adversaries: the loyal Dr. Watson, the nefarious Professor Moriarty, Inspector Lestrade of Scotland Yard, Mrs. Hudson, and Irene Adler, the only woman to outwit Holmes. Sixty interchangeable heads portray a variety of actors who have played Holmes and Watson over the years."
Yes, you read that correctly "Sixty interchangeable heads" featuring a variety of actors who have played Holmes. Yes, my curiosity over the representations of actors is strong enough for me to order this ephemeral bit of silliness just to see who made the cut. Expect a follow-up when I find out!
As for THE HOUND OF THE BASKERVILLES COLORING BOOK and the SHERLOCK HOLMES ACTIVITY BOOK, I'm afraid that you're on your own!
