This is a vintage Rawlings leather catcher's Mitt PML.
The reddish-brown leather mitt is for left handed catchers. Most of the writing is worn off but you can read "Rawlings and PML" inside, "Rawlings The Finest In the Field" across the top, and "Rawlings" on the button.
It measures approximately 7" long and 9" wide.
This mitt is in good pre-owned condition with wear from use and aging.
