Authentic vintage (circa 1970s) Dodgers crew neck sweatshirt.
I don't know what technique was used by then to print this, but I don't think it is screen printed.
Has that neat, old school technique with the thick printed letters (see close up pics).
There's no tag/label but it's a kids / youth size . Could possibly also be worn by a small adult female.
See photos which show measurements.
A rare item!
