Here are the cards that carried the stamps below. The top one is a photo from a Brazilian postcrosser named Jessica, a student who likes photography. The shot is of her town square, a popular place, she writes, to walk and talk. The bottom one, from Mrpotani, advertises an ice cream shop in San Francisco that offers offbeat flavors, such as olive oil, chai chili lime, white miso, blood orange, candied chestnut, and on into the night. That last is not a flavor, though there is one called secret breakfast. On her last visit to the shop, Mrpotani tried the brown butter and loved it.
