I think that's a mid size.
As a side note, Paul McCartney was the Walrus.
Here are the lyrics from the song "Glass Onion":
I told you about the walrus and me, man
You know we're as close as can be, man
Well here's another clue for you all
The walrus was Paul.
.
It’s up for debate though. Some say he was just playing with words and the song I am the walrus revealed the truth. I am the 2,789th beatle if you outrank me I will give this one to you. Remember, after glass onion, in one of his solo songs he said, “I was the walrus, but now, I’m John.”
I think I seen other pictures where it looks full size?
