Ornate D J Gallery
This is a stamp with a very ornate D and J. There are lots of fancy swirls and lines around the letters. I've decided to show the example on the left as a larger sample of this stamp because the stamp is difficult to see at the smaller size.
Interestingly, the example on the right has D A J with an A in the middle. Then at the bottom of the card it has just the D and J like with the other examples I've seen.
