This is a trucker hat. With a Montreal Expos Larry Walker baseball card printed on the front. From the eBay listing description:
We acquired this rare cap and many others from a direct family relative of LARRY WALKER in Maple Ridge, B.C. – his home town! :)
Personally, I’m not the biggest fan of the trucker hat style but I do think this is a brilliant idea as far as cap logos go. I just don’t think I’d drop 22 bucks on it (plus shipping and handling!).
Hat tip to Matt Clapp of Sharapova’s Thigh and his readers, 89% of whom would rock this style as of this writing.
