Thank you for viewing. This is a reference book published by Toyota Motor Corporation in 1984. It's an old book, but it's educational. The photos are retro. As it is an old book, the cover has deteriorated, and there is overall age-related wear, but there is little damage and it is fine for reading. I don't think it's something that comes up often. I appreciate your understanding of used books. A specialized book on materials published in 1984 by the Toyota Engineering Society. - Title: Knowledge of Materials - Publisher: Toyota Engineering Society - Publication Year: 1984 - Language: Japanese Thank you for viewing.
