One thing I enjoy collecting are old wooden hangers that have advertising on them. In the forties, many hotels had their name printed on their hangers. For some reason, I just love these old things! I like their practical value, as coats and other heavy items need a sturdy hanger, and I also enjoy the nostalgia of that era. Some high-end stores now sell very expensive -- and very handsome -- hangers for men's and women's suits. Lovely, but I'll take the old ones.
I've never heard of anyone else who collects these.
