Found Wallpaper

They are working on my bathroom right now, and there were 3 different wallpapers lurking under the layers. First up, the most recent, from the late '60s, early 70s, maybe:

Please note that there are two different different depictions of pink swans, one with a blue bow...does this conotate maleness?

Second is a beautiful, simple all over pattern from maybe the '40s:


The final pattern is a hand-printed fish border (which appears to have been accompanied by a peptobismal pink and black sponge paint job!!!!) :

Despite dubious design pairings, I am very charmed by the pattern. I wonder when it dates to? It is the oldest, on the bottom layer of renovations...maybe the late '20s, early '30s?
