Thank you for viewing! This is the "Introduction to BCL Book" (1979 edition). I bought this during the BCL boom at the time, and it's now a hard-to-find item. If you're a collector, please consider it. If you have a desired price, please let me know in the comments section. The book has some wear and yellowing commensurate with its age, but there are no man-made scratches or folds, and the condition is relatively good. However, as it is old, please purchase only if you understand this. - Title: Introduction to BCL Book 1979 edition
