I have a late friend who offered to give me his entire garage full of thousands of different beer cans lining three full walls to the ceiling. I have no way of knowing how many there were, and how many countries they were from but it took at least 6 alphabets or ideographic systems to name them: this one, Greek, Cyrillic, Armenian script, Chinese, and at least one of Hangul, Hebrew, or Manchu. The last is not clear in my memory. I have no idea what he did with it before he died. It was a very colorful and interesting display!
Used to collect books. As a kid, rocks. Nothing really at the moment, though I still have some of my favorites from the books.
As a bookshop owner, I collect pages. I recently disbanded a ballpoint pen collection. The ink had dried. In the pantry, I have an assortment of soups and beans.
