Heres some of the QSL cards I have received along with a couple of the ones I have designed and sent out.
My Designs

This was the first card I designed and printed off, haven't sent any of these ones out yet.

Currently my main QSL card design. This one was the most popular design when I polled my coworkers and friends.

Another
design I made up and printed, not as popular as the State Flag one,
when I polled people I knew on thier favorite design, though it was
more popular then the plain design I first came up with.
Some of the Cards I Have Recieved

The
very first QSL card I ever revieved. This was an Eyeball QSO with one
of the members at the Lapeer County Amature Radio Association. I
initially gave him one of my QSL cards at the September LCARA meeting
and he returned the favor with his card at the October meeting. Raymond
is a great guy and has offered to help me get into packet modes if I am
ever interested in gettng my feet wet with some of the various modes
like FT8, JT65, PSK31, etc...
