Background: The Delicioso stamp dedication ceremony is being held in conjunction with Salud y Sabor and the National Hispanic Cultural Center. The event is a free evening of food, art and entertainment aimed at providing families with an opportunity to connect around nutrition, cooking, healthy lifestyles and culture.
The Delicioso stamps feature bright and playful illustrations of tamales, flan, sancocho, empanadas, chile relleno, and ceviche. The booklets include four of the tamales and flan designs and three of each of the other designs. The names of the six dishes appear in a festive font above each mouthwatering image. Each illustration was created by applying multiple layers of acrylic paint to textured boards, using sandpaper to reveal the hidden layers and give the designs a worn, vintage look.

Artist John Parra designed the stamp artwork under the direction of Antonio Alcal´a;.

The Delicioso stamps are being issued as Forever stamps. Forever stamps are always equal in value to the current First-Class Mail one-ounce price.
Followers of the U.S. Postal Service’s Facebook page can view video of the event at facebook.com/USPS. The public is asked to share the news on Twitter and Instagram using the hashtag #DeliciosoForever.
