Baltimore Orioles helmets from American Baseball Cap Company are exactly like the ones worn on the field by Ripken the Great. Size 7 3/8, they sport the elusive “Cal Ripken, Jr.” signature on the brim in mint silver sharpie. Also, each helmet carries the traceable hologram of Major League Baseball Authentics. There are two-dozen signed helmets in this lot and too good to pass up. Mint.
