Description

Vintage 80's 90's Lotte Giants (KBO) Korean Pro Baseball Cap. Fitted Size 21.
Pre-Owned, New condition.  Clearly stored for some time, clean and neat inside and out.
I am new to Korean baseball caps, so please double check my size info if you need to.  The label is marked "21" which should be the size.  Using a cap size chart, 21 refers to head size in inches (slightly odd to be inches for an asian hat) - this seems correct given the conversion from 21 1/4" is a 6 3/4" hat (So this hat for sale is a little smaller, which seems right).  This puts it in the "Youth" size territory, although the brim clearly looks like an adult size - added pictures with a tape measure.  Across brim is 7 3/4", and the last picture is 8 1/4".
The cap is clearly professionally made, although there is no company (maker) label, only a typewritten team name and size label.  I found 4 different KBO caps together, same condition and labelling.  The logos are not embroidery, but cut pieces of felt.  The inside headbands are vinyl or faux leather.  I wonder if the caps are prototypes, but I was not able to verify this, and I am NOT claiming this.  (I'd be glad for more information if you have it, please message me.)
I have a nice selection of vintage caps/hats listed now (including KBO, OB Bears), both sports and non sports.  Please take a look when you have a minute.  Thank you.
