He’s the nutball who used to work at the Apollo Bookstore years ago when it was on Newport behind Coast Music at 18th. He often dressed in a similar costume, but even more extreme. Frequently he would be in a full Scots Guards uniform from the 19th century, or a WWI soldier’s uniform, while on duty at the book store. At the tender age of 14 or so I was constantly lectured by him on the joys of being a “scotsman”, and of military reenactment, and how it was manly to wear a kilt, etc.
This has to be the same guy, just aged appropriately. Mustache is now gray but I’d recognize the manic grin and the tamoshanter anywhere.
