Post Card Design

Hey everyone, here's a few designs of the post card that I have going. I placed them in a box that is 6 x 4 1/4 in. the size of the post card we will be printing. I didn't have written down the correct shade of blue so I just chose one to put in place of that temporarily. Let me know what you think!

There's a black and white version and a blue and white version.
