This romantic card shows a coupe kissing on the beach. The card was mailed in 1909 from Atlantic City to Philadelphia with a message that simply says “You know.”
I guess the sender found their pebble on their trip here. 😉 I looked to see if “Pebble” was some sort of pet name people used to use, but I am pretty sure it is not. Also, it is weird to think of the beach being full of pebbles to sort through- doesn’t seem like it would be a comfortable beach!
