you need to provide more details. You said you are a real state and want photos of food? who's the client? what deatails apart from the contact details need to go on the postcard?

Yes, I am a real estate agent. I want the recipients of the postcard to be highly like to save them and not throw them away. A postcard with a recipe on it and a photo of the finished recipe is more likely to be kept, especially by women. I want a postcard TEMPLATE that has my contact information and photo, permanently posted on the back of the card, with a area that I can write in a new recipe each month, as well as change the photograph of the food.
