The ground was too cold when I buried the papers so I couldn't dig a deep enough hole to include the metal box.

I may have taken the challenge too literally. My packages were buried in the garden and some papers almost totally disintegrated. There is enough however, to make something from the pieces. I have to figure out a way to get the underground wildlife off them before I can bring them into the house to work with. Suggestions welcomed.
The fabric did well - I will try this again with fabric - colored fabric, fabric laid with rusted metal, white fabric - this has opened good future possibilities. I need the time between now and August to clean up the papers, dry off the mold and de-bug them. Check back on August 1st for the third part of the project - displaying art made from the project papers. Thanks Seth!
May 2 - Got some of the papers laid out a little and opened up - they look promising!
