Some non-repro naughty postcards I found that have a decidely 60's-on-the-cusp-of-70's feel about them (click for an enlarged view). I love the backgrounds and the Will Elderish style. The reverse sides are completely blank, offering no information on the artist, whose signature appears to read: "Asfan". Oh, really?
update: Turns out, to my great disappointment, that this artist's name is 'Aslan'. Link
