Hello, I found his rust-red 100% felted wool hat made by Sonni San Fransisco. I've done a lot of research on them and think that the hat I have is possibly from the 1960s. The label is embroidered, not printed, which they started to do in the 80s. But the inside is not lined, which makes me think it is younger. The feathers weren't in the greatest condition, the two longer ones were sticking up in the middle/top and were quite broken, so I cut them and attached them to the side. I wonder if there were possibly more of them once. I'm also having a hard time reading the inside stamp. I can make out 'Glenover ..?.. felt Made in Poland? 100% wool' but I'm not 100% sure.. Any help is much appreciated!
