I know this is probably a shot in the dark, but I can seem to find anything particularly useful through good ol' Google. I recently acquired a silk jockey shirt in a shadow box and I want to find out what it might be worth. I have heard that the design of the shirt is distinct to the jockey/stable so based on what I have, how can I figure out where it came from? It is royal blue with a gold "bow tie" at the collar and three matching gold diamonds going down the shirt on each side (6 in all). On the wearer's right side there is a black diamond with a vertical white strip in the middle of it that is placed between the top two gold diamonds on that side. A matching black diamond w/ the white vertical strip is on the top part of the (wearer's) right sleeve. Obviously I know almost nothing about this stuff. My buddy thinks its from the 30's or 40's if that helps at all. If you might have an idea as to the origins of this shirt or know where I might be able to easily look it up, I'd really appreciate it. Thanks!
