This might be the rarest Simpson Shaving Brush of all time? I picked this up many many years ago and it has been sitting stored since then. I've never used it and just take it out every once in a while for my viewing pleasure. It doesn't appear that it's ever been used. I've only ever seen 1 other in all the years I've been collecting. I've often wondered at how large of a run of these they made and what they cost originally. It's a super neat brush that I just had to share. If you know anything about the background of this one I'd love to hear. Enjoy!
