A Mailbox Mystery

I recently discovered the delightful, upbeat blog of Mary England, called Lust for Life.

Mary is a 20-something, mail-art loving, positive-energy giving blogger who lives near Baltimore, not far down the road from me.

She recently gave away some Hallmark postcard packs she found while thrift shopping, and I was lucky enough to win one of them.

Because Mary loves mail art, just like I do, her package to me was lots of fun:

I think the very best part was her Moo card, which listed her name as "Mary England, Life Enthusiast"...how great is that!?!

And the postcards were very sweet:

Now here comes the mystery:  The envelope arrived with the bottom slit open; however, it did not appear that anything had slipped out.  Included in the contents were a handful of photos that looked like they were taken at a prom in the 1980s; the back of the photos, however, said that they were developed at WalMart just this month.

When I asked Mary about where she got them, she didn't know anything about them!!

Now, could it be possible that someone opened my mail to put something into the envelope, rather than to take something out?  Is this some sort of mail prank? 

A mailbox mystery, to be sure.

I still haven't heard from Bonnie, the winner of my recent giveaway. If I haven't heard from her by Sunday, May 20, I will be drawing for a new winner from the original entries.
