My mom was going through boxes and found some old books, including a few of mine. She asked if there were any I wanted to keep and I immediately picked out my old copy of Insects: A Golden Nature Guide from 1956. Haven’t opened it in close to 35 years and I live on a different continent now, but it’s one I’d like to flip through again at some point in the future.
For what it’s worth, I also still have the first book I bought with my own money as a kid – a guidebook to dinosaurs.
