Style 7, the Postcard. Round 4: the formats
The approved set on the taller boards. A postcard is a landscape object, so it changes shape rather than stretching. Portrait keeps the back at the top with larger type and lets the front peek in below it: the photograph with its caption in the white border. Story shows both sides: the front on top, the photograph and the line on its band, and the back under it carrying the rest of the message, the postmark, the two stamps and your address. The front card from the square set is the story's top half, so it does not repeat here.
What to look at. Whether the two sides read as one card in story, and whether the peek below the portrait earns its place. Pass or note each by name and format.
