The Boston Celtics play on one of the most recognizable wood floors in the world, but the notoriety wasn’t intentional. The floor was commissioned in 1946 while the US was experiencing a lumber shortage in the wake of World War II. Using scrap lumber originally cut in Tennessee, manufacturer Boston Lumber Company opted for the distinctive square parquet pattern in order to maximize the yield. After years of play and having hosted an astonishing 17 NBA championships, the court was disassembled in 1999. Today, pieces of it can be had for between $25 and $125 from sports memorabilia sellers. A newer replica of the floor keeps the history alive at TD Garden Arena.
