I'd say it's from between 1890-1910...would guess 1895 if I had to pick an exact date....based on the black ends of the bats and general flavor. I noticeed the chest protector does not look like a pneumatic. Overall I'd say it's one of the best baseball hankercheifs I've seen.

I got a similar handkerchief at the 2006 National from Kirk Kovaks for $500.00. It has multiple sports including baseball from about 1870...It has advertising for Standard Shirts which traditionally adds value...Kirk was asking $800.00 as I recall..You can see it in a link in the last paragraph of the page linked above.
