After I read through four copies of 1930, I found out I didn’t need to read multiple copies of the same year once I’d determined there was a complete and intact copy. Also, I wanted to increase my speed, and fewer pictures caught my eye, and also yearbooks without page numbers left less idle focus for sightseeing when I was trying to determine completeness by alphabetic continuity. Yearbooks with page numbers I could buzz through very quickly if I wasn’t also doing costume research, so the decades I don’t expect to be reenacting went by pretty fast.
So… After the thoroughness of the 1920s, here’s the early 1930s. Hair gets less interesting to me, but the necklaces get pretty excellent. (This trend fading is a lot of what made my interest wane.)
