Canvas Photo

About a month ago, I delved into the world of Groupon when I bought a coupon thingy to buy a discounted 16x20 photo canvas.  While I have until October to use it, I hope to get it ordered in the next few weeks.  Now comes the hard part, picking a photo to have printed!  I've narrowed it down to 10 choices, most from our travels or the wedding, but I thought it'd be interesting to get your opinion about what we should hang on our wall (when we get a wall to hang it on of course).  So, which photo do you think we should have printed?

Acropolis, Athens, Greece

Leaning Tower of Pisa, Italy

Temple of Poseidon, Sunion, Greece

Pompey's Pillar, Alexandria, Egypt

Water treatment plant, on campus

Engagement photo

Wedding Photo 1

Wedding Photo 2

Wedding Photo 3

Wedding Photo 4

So, what's the verdict?
