Hello To All:

I've searched high and low, and cannot identify this logo.  Please see photos.  I appreciate any assistance.  Thanks!

Here are the hits I got from replacements.com.  Possibly it's the Ralph Lauren but you'll need to check the mark to be sure.

Thanks for looking. The plaid look is the same,  but Ralphs are marked with RLL.
