Paper dolls from Spain

I love Googling "recortables," cut-outs in Spanish, and finding little gems like these. Is there a collector out there who can present at the next convention in Phoenix on these paper dolls? I would love to know more about them: publishers, artists, where they were sold, how many were published... Recortables Bruguera is the most common of a certain vintage, 1940s-1960s, I think.
