Potter Mention in Stephen King’s Latest

Loads of TLC readers have informed us that Mr. King, who has repeatedly praised the Potter series, has (once again) referenced Harry in his recent book, The Dark Tower (book 7) (click to read):
“Check out the crate-lid,” Jake said when they joined her.
Susannah had set it aside; Jake picked it up and was studying it with admiration. It showed the face of a smiling boy with a lightning-bolt scar on his forehead. He was wearing round glasses and brandishing what appeared to be a magician’s wand at a floating sneetch. The
words stenciled beneath the drawing read:

PROPERTY 449TH SQUADRON
24 “SNEETCHES”
HARRY POTTER MODEL
SERIAL #465-17-CC NDJKR
“Don’t Mess with the 449!”
We’ll Kick the “Slytherin” Out of You!

We’re also told there’s a domestic robot in the book named ‘Dobbie’.

Thanks to all the Leaky readers (and King fans) who wrote to us – in particular Steve for the “Dobby” tidbit and S.Chang for the transcription.
