The product is a lot of two vintage activity books titled "How to Build Patios and Sundecks" from the Easi-Bild series by Donald R. Brann. The books were published in 1970 by Easi-Build and are in English. They provide instructions on construction, home improvement, building plans, and woodworking related to patios, sundecks, cabinets, and stereo systems. The books are in paperback format and were likely manufactured in the United States.  Thanks!
