Timeless looking flapless, fiberglass helmet from the late 1960s or early 1970s. Made by American Baseball Cap with 7 3/8 sticker inside. Appears that this helmet was possibly worn by several players with "33" on back and "4" written inside. #33 could have been Dave Campbell, Gene Lamont or Frank Howard, while #4 could have been Tom Tresh, Kevin Collins or Aurelio Rodriguez. Helmet has large crack on the right side and most likely the reason it was taken out of commission.
