They sure did and not just the Yankees. This is easy enough to confirm in period images that capture the helmets from the side or from above. But these designs changed over time by team, along with other facets such as the number/location of vent holes in the crown of the helmet as well as information contained on the interior ABC sticker. When studied in some detail and considered in total, it does offer one the ability to establish some objective date ranges for the helmets.
