These playful risographic postcards are a reminder of the phenomenon of collecting C-shaped plastic hooks in the communist Czechoslovakia. I have used my own typeface Plastic (created in cooperation with Jitka Janečková), which is based on the C’s.
The C’s were originally manufactured to be hanged as decorative chains in windows and doors (as they can be linked up in chains), but spontaneously became a popular toy among the kids growing up in the 1980s. More letters and geometric shapes were added later. The kids used to collect the C’s and create colorful bracelets and necklaces. They have even traded them, meaning that each shape, colour and material had a different value. They even “paid” with them for comic books or other valuables. The C’s became an unofficial currency for kids in Czechoslovakia. They caused a national collecting craze. It became impossible to buy them in the shops so the parents had to “use their connections” to get them. If you had no C’s, you were not cool.
