Once described by Jimmy Page as both his "mistress and wife...
except it doesn't ask for alimony"
His "Number One" Gibson Les Paul is—without question—
one of the most iconic guitars in the history of rock.

The guitar which he purchased from Joe Walsh
who was in the James Gang at the time
In 1969 during one of Led Zeppelin's early U.S. tours
has been closely associated with Page for decades
It was heavily featured
on the majority of Led Zeppelin records and live shows.
In the May 2012 issue of Guitar World
Walsh spoke about the transaction

"I laid it on him and said, 'Try this out'.
He really liked it, so I gave him a good deal, about $1,200.
I had to hand-carry it; plus I flew there and everything.
So whatever my expenses were, that's what I charged him.
I just thought he should have a Les Paul, for godsakes!"

Due to a refinishing job commissioned by Walsh
the serial number on the guitar was removed
which has led to many a debate over the guitar's year of manufacture.

However
due to the neck profile
most experts concur that it is likely to be a late 1959 model
or an early 1960.

Page gives us an up-close look at this special guitar
just before it was spirited away by Gibson
to be copied by the company's custom shop.
