The Kodak Brownie Twin 20 looks like a jolly, happy little camera (front on it reminds me of the dog, Brian, from Family Guy) and was introduced by Kodak in April 1959, it was made at first in New York, then later on in England during the early 60’s, until 1964 when it was discontinued. Cost wise in 1959, they would have been around $11 (£4.00)
(I don’t think I need to go into detail about Kodak, they are one of the biggest producers and innovators of photography and photographic equipment – there’s far too much to detail here – I’ve added a few excellent links at the bottom if you do want to learn more)
