Dress Shirt by Van Laack

I bought this shirt in Germany sometime during the mid 80's. Even that old, this shirt appears as virtually new. Seldom worn (gained weight) and has been dry cleaned. Regarding size, it appears to be either a 39 or 40 in EU size. I can state that this shirt is a LG as I am almost 6'2" and at the time about 175-180. Very beautiful cotton dress shirt.
