The first two bonnets are, I think, early 1850s maybe late 40s. The two next black bonnets are late 1850s/early 1860s spoon bonnets for mourning, the first one is made of black crape, which a lot of mourning collectors like - the second one is missing the bonnet ties but its the same as the black crape bonnet. The next two straw hats I am interested in... And the rest are all 1940s/50s summer hats. Like the last one the best with the green velvet flowers.
