Brownie is the name of a long-running popular series of simple and
inexpensive cameras made by Eastman Kodak. The Brownie made
low-cost photography popular and introduced the concept of the
snapshot. The first Brownie was a very basic cardboard box camera
with a simple meniscus lens that took 2¼-inch square pictures on 117
roll film. With its simple controls and initial price of $1, it was intended
to be a camera that anyone could afford and use, hence the slogan,
"You push the button, we do the rest."
