Perhaps you could design it to be a tombstone. I made a Halloween countdown tombstone that people seem to enjoy. Dense core foam where all the lettering is carved in except the numbers, they are changeable. Perhaps you could do the same and just leave the year to be changed. I put it out 30 days in advance with a skeleton dressed in shorts, tropical shirt and sunglasses. He holds a leash and skeletal dog. It has lasted for years.
