Due to the career and how I like to dress, that definitely a pocket square. I have one in my breast pocket often.

They have become bigger and smaller because of fashion changes over the years. I probably have about as many of those as I have ties (100+) and some are tiny (10" square) and some seem huge ( up to 22" square). I often buy vintage because I like the quality and the look.

Looking at the colors, size, and print, my assumption would be it would be from somewhere in the mid 60's to mid 70's. They are worth more if they are from a very quality maker, hand painted silks or really bright and appealing. Unfortunately, that brown really dates it to the period and makes it a hard sell for someone who wanted to use it. The simplicity of the retro print and the colors makes me think it was a japanese maker for a department store item in that period.

Squares are one of those things that are not worth more than someone feels it is worth to them and their passing fancy at the time without a big name maker (I felt if you saw a maker name it would have been mentioned). Likely I would think between 10 and 20 bucks because the baseball print makes it more appealing. A common square of that period is usually under 10. I would just hold on to it, if you have a dark blue suit and some brown shoes you could take it for a stroll one day.
