Jacket, If You're Real, Where's Yer Bin?

The heading's a throwback so to speak to my last post. (They talk like that in the village I come from. At least they used to. Now they're all posh and talk 'proper! All fur coat and no knickers as they used to say!) But I digress. 'Where's yer bin' refers to an article of clothing that hangs on the door of the 'bar' in my 'outhouse' to which I frequently retire when I wish to let the world go by. This particular item is a jacket I bought at a a jukebox fair in Kempton Park a couple of years ago. I like this jacket, I am intrigued by it and I would love to know more about it. It is undoubtedly from the USA. It has the label 'BUTWIN, 'The Champion of Jackets, Minneapolis, MN. Made in the USA. (There is a label inside, not very clear that seems to say union made in USA, ACTWU plus other numbers also not very clear that may be batch numbers.) I presume it is college student apparel. I also presume it was owned by a male rather than a female; the fact that it carries the 'monika' Ken is surely proof. One reason I bought it being a 'Ken' myself! And I presume its original owner liked his jacket or else why would he add adornments. Is it the type/style of jacket still worn or can the 'more with it' out there date it particularly to an 'era'. I can picture young 'fella my lad' Ken proudly showing off to the girls in his fabulous jacket. Oh to be young again! What is the significance of the 90 and the 'sergeants' stripes? (Not really sergeants stripes?)And presumably the letter H is important. The badges too are interesting. Do the 'young uns' buy them or are they awarded? One suggests the badge holder is special. (Badge indicates 'Outstanding High School Students of America. OHSA.) Of the four other 'medalions/badges', three are marked Solo, one Ensemble. By browsing the internet I am aware of Minnisota High School, but have no real awareness as to the scale of American secondary education and Minnisota High School in particular. I assume 'my' jacket perhaps once graced the back of a diligent, hard working pupil of this establishment. Who knows, and where are you now, my boy. What did those far off days do for you? The whole thing reminds me of the films Grease and Saturday Night Fever. Please remember, what might be obvious to you is not necessarily so to myself. But the power of the internet being what it is, who knows. And the last post did talk of the world being a global village. Any information gratefully received.There again it could of course be a copy mass produced to sell to gullible old English geriatrics. The world is full of copies. I have amongst my 'treasures' tickets to both Elvis and Rolling Stones concerts. I even have greeting cards sent by Hitler at Christmas, 1943. Not to me I hasten to add! Genuine, I would have thought no chance. But in a way it doesn't matter. I can still shut my eyes and dream of Ken 'walking the walk' presumbly years and years ago. (You might find the post I did on the 17th February interesting. 'All Is Often Not What It Seems.' 17th February 201o. This concerned the poem Desiderata by Max Ehrmann. I was taken in by this poem, origination, the grand old US of A.) Does lightning ever strike twice.
