British artist James Cook has gained international acclaim for his stunning drawings featuring thousands of letters and symbols printed from vintage typewriters.

Footage captured at his London studio on Monday shows Cook meticulously typing away as he works on his latest piece, an incredibly detailed portrait.

"So I started creating typewriter art back in 2014, and it began as basically a school project to begin with, which somehow ended up becoming just a hobby really," Cook explained.

"Normally, a drawing will take about a week to do if it's a smaller size, like the ones behind me, but I've spent two to three months working on just one piece," he added.

Cook says his most ambitious work was a picture of the Lower Manhattan skyline, which was commissioned as part of the 400th anniversary of the city.

"It's taken me about two to three months to complete and has probably somewhere in the region of about a million individually typed letters, numbers, punctuation marks," the artist explained.

The London-based artist has now amassed a collection of over 100 vintage typewriters, with a device used to print sheet music among his most prized machines.

"What is so special about this is it contains musical notes instead of the alphabet, so this was built to improve how musicians would write sheet music, and this is an incredibly rare machine," Cook said.

"They only built about 50 of these, and within the inner circles of typewriter collectors, I had to trade an Arabic typewriter, as a part-trade, just to get this machine," he continued.

Cook says he can create about 50 artworks a year and sells them through his website. The artist only runs limited prints ranging from roughly 150 to 400, depending on the piece.
