I got notified of one today that fills my need to read other people's mail. It's a ton of postcards from the Edwardian era, and you get an image of both sides of the card. I've only done a couple, and there seem to be two parts to the project, one focusing on the cards themselves and how far people send them (within the town? across the country?), and another one focusing on the people writing and sending, but I haven't tried that part yet so I don't know what they're looking for.
All this to say that the second card I read charmed me by being addressed to a Mr Albert Newell, Violinist. However, the writer was sidestepping an apology for creating some sort of uncomfortable situation between the recipient and another person, who'd evidently had a falling-out.
edit: In this one (click the "2" underneath or go to the Imgur version I uploaded), "P.C." seems to be "Post Card," but I have no idea what "O. B." is, especially given that "Shrimps" are offered as a substitute.
