Plywood has been made for thousands of years; the earliest known occurrence of Plywood was in Ancient Egypt around 3500 BC when wooden articles were made from sawn veneers glued together crosswise. This was originally done due to a shortage of fine wood. Thin sheets of high quality wood were glued over a substrate of lower quality wood for cosmetic effect, with incidental structural benefits. This manner of inventing Plywood has occurred repeatedly throughout history.
