In the country I regularly found miniature shells, broken pottery and glass, antique glass bottles and glass stoppers, ancient blunt headed nails, and even rusted old tools.
In the city, so far, I have found a used condom (not pictured), an unused condom, pop bottles, beer cans, a lipstick, and a new spoon.

That is, until last Sunday...
I found what appears to be an old broken bottle neck and a newer piece of a china cup.

Did my friend hide those in my city garden to surprise me?
