This large modern button could have been made yesterday. It is probably from the first quarter of the 20th century. It measures a hair over 1 & 1/2 inches and the mounting tests fine silver (sterling). The painting is on coarse absorptive paper under glass. I have not seen another like it, so it may even be unique, perhaps a gift for a sailor (maybe THE sailor. Notice the sloops are moving on in light air while the yawl looks stalled.) It is fine quality painting and in excellent condition.
