Got in a bunch of the miniature AD&D books. Always fun to get a comparison photo with a full-size rulebook.
Here’s the story, copied from our reference site:
For a brief time, a company in Italy called Twenty First Century Games produced licensed miniature reproductions of classic AD&D publications. Each has been exactingly reduced to a size that will fit in the palm of your hand. Yet, each is usable & readable, though a magnifying glass or senior citizen magnifying sheet may be handy!
