These cards are 5 ½" x 7 ½" with matching envelopes. The paper is museum quality.
The inside is blank so you can write on them with pencil, pen, etc.
Photos may be vertical or horizontal on the card depending on best composition.

The back of the cards will look like the two examples below.
I will add a line that says, "Made especially for (the recipient's name)"
or any other line you prefer. The red arrows will not be there.
