Thanks Jack! You made me laugh.
On the front are three cartoon pictures. The first picture is of a nude guy carrying his stuff toward a nude beach. The signs nearby says, "NUDE BEACH" with an arrow pointing to the water. The middle picture shows just the sign and beach. The last picture shows a crowd of nude people running away from the beach with scared looks on their faces. Sadly, all the guys are young and muscular.
On the inside of the card, it says, "There are some things that people our age just shouldn't do." "Try not to think about it, and have a Happy Birthday!"
I just checked and yes, the card is from Hallmark.
