Randomly select one card with image or object and one card with word or concept. Find a new connection, based on the content of the two cards, and design posters to express the new concept with black and white.
After getting a set of word and image, I listed all the words that I can think of about the card's content. Then, after rearranging and combining these words, a new word came up. Based on the word, the poster was created. I use the cards as the common element of the series of posters.
