Could you provide a photo, or a link to a photo, of the image?
The only image that fits your description that I can think of off the top of my head is this one:
Love-Memory-Treasure by sandijcrafts - Cards and Paper Crafts at Splitcoaststampers
It's credited here to American Art Stamp. However, I purchased the same image from Lizzie Anne Designs before they stopped doing business.
edited to add: Sue was typing the same time I was! However, even though the link she provided shows the same image I linked, I don't see anything that confirms that the stamp is from SU.
