Vintage treasure

I took a break from the digital world today and started sorting out the spare bedroom which has been a dumping ground for random things both pre and post my move from Switzerland. I stumbled across a file of vintage millinery magazines I remember buying many years ago. Some of them still have the original patterns included. There are no dates on them, but from the hat styles I am guessing they are 1920-1930s. I’m hoping I pick up some tips!
