Please if you find anymore, please add it to the list.
Plus obvious spoilers for all adaptions
Number One:
The cow is called Mrs Udderson, an obvious pun on Mrs Hudson, Sherlock’s landlady.
Number Two:
It is rather small and annoying since I could not get a good screenshot of it but just behind the pencil it says “Baker Street”, the street where Sherlock and John live.
Number Three and Four:
There are actually two in this single frame. I, in fact, didn’t notice these two on the first watch. Wisteria Lodge is from the short story of “Adventures at Wisteria Lodge.” The only reason I got this one was who calls their flower shop a “Lodge”? Anyway the story is about some guy who was beaten to death in Wisteria Lodge, idk, I’m too lazy to explain it.
The next one is a blink and you will miss it. You see that shape on the left side of the picture on the wall. It is one of those security thingy-a-bobs. It was difficult to zoom into the picture without making it fuzzy, but what it says is “Sure locks for Homes”. Get it? I hope you do or else I feel sorry for you. Also Also, you might also remember this pun from the end of Pixar’s Inside Out. (the part with the cat and the dog.
Number Five:
This is first of all Sherlock’s mind palace. (Those who watch the show will get it).
In the corner just above the train there is a door with the address 221B. Of course it is Sherlock’s apartment. It also might be foreshadowing to Irene Adler’s hideout (will speak about later).
Number Six:
Ok I don’t know how much of a reference this is but for those who actually watch the show they will recognise the waving cat from the second episode (the blind banker) from the first series.
Sherlock and John follow a clue to a shop where the owner said that a waving cat would be the perfect present for a wife.
IDK if this was intentional but I found it interesting.
Number Seven:
The Hound of The Baskervilles can it be more obvious?
Number Eight:
Doyle’s Doll Museum, so named after the original writer of Sherlock Holmes, Sir Arthur Conan Doyle.
Number Nine:
Again the reference to Apartment 221B. Also opened by a bear named Gregson. Gregson was an officer in the police force in the books.
Number Ten:
I probably missed a lot between these two scenes but this is the next one. The company’s name on the box is called Moffat and Gatiss. Die hard Sherlockians would recognise this name from the TV series. Mark Gatiss and Steven Moffat are the producers and Gatiss acts as Sherlock’s brother Mycroft.
Number Eleven:
Again I don’t know if this is intentional, but the way that Moriarty presents himself resembles the way Moriarty in Sherlock presents himself at the end of the third series. I think I am grabbing at straws with this one.
And Number Twelve!
The fall! It is a reference to The Final Problem which in Holmes fakes his own death at Reichenbach(?) Falls, also ultimately killing Moriarty.
So what did you think guys? What else did I miss? I’m pretty sure I missed a lot of them.
