Hidden (no) Treasure

Are cigarette packs the builder's version of a time capsule?

Removed the ceiling of the kitchen today (which really helped the aches and pains from yesterday's exertions).

Also found:
- one saucepan
- 2 pencils
- 1 chisel
- 1 birds nest
- fragments of wasp's nest
- one page from The Financial Times (no date)
