We see what we want to see and believe what we want to believe. What we see at a distance is not the truth. One day, there was a couple at the movie theater. The couple was buying popcorn and talking about saving the movie ticket stub as a memory. However, they threw away the popcorn receipt they received. Why would they keep the movie ticket stub but throw away the receipt for the popcorn purchase? The event of buying the popcorn was also an important page of our date. I wondered if I could give new value to the receipt and recycle the memory. A receipt may be filled with memories that we take for granted and forget. The accumulated images of someone's time and logs may be creating the wisps of society. Receipts are a material that cannot be recycled. The 54,000 tons of receipts consumed in one year in Japan are equivalent to 13.5 billion sheets of A4-size copy paper, which also contributes to water pollution and deforestation. Isn't this a sign that we are neglecting resources and memory? I feel frustrated. I used receipts collected from all over Japan and collaged them with a unique material to prevent deterioration. My intention is that decades from now, when receipts are no longer available, our life logs will remain as cultural documents.
