I did these artist trading cards a few years back and still love them. A friend was cleaning out a house and had a pile of trash (which I offered to look through before he tossed it). I salvaged a magazine from 1957 which ran an article on "Glamour Secrets for Girls" which I thought was pretty amusing (one particularly good one: "Maybe you can't be a raving beauty but you can have come-hither charm").
At the same time I found a vintage pamphlet advertising different hair colour. I put the two together and glued them on top of patterned wrapping paper. To complete the ATCs, I made tiny ribbons for their hair our of 1/4" velvet ribbon.
