It's made by millions, it is easy to find and it's cheap: your analogue friend called the Agfa Clack! If you don't have one, start checking out the flea markets, because this camera won't let you down. It's a perfect companion to your Lomography camera collection.
My enthusiasm for analogue photography has lead me dig through my mum's, dad's and grandparent's old photos to see their family and holiday snaps from the '30s to the '70s. The good ol' days when digital was just an adjective associated with fingers.
