We don't do this very often at Sight Unseen — post about the same subject twice in the span of two weeks — but in this case, we couldn't help it: When the young Portuguese graphics duo Studio AH–HA submitted their answers for our recent Up and Coming profile, they included eight impeccably styled photos of their personal stationery collection, and we couldn't bear to let the images go to waste. There are few things more beautiful than old paper goods, as anyone who's ever perused the goods at Present and Correct, or the mountains of vintage office ephemera available on Etsy, can surely attest. So we asked AH–HA's Catarina Carreiras and Carolina Cantante to share the stories behind the objects in the photos they shot for us, many of which they inhereted from Carreiras's late grandfather.
