Aside from the basic composition, I can't find enough art historical references to justify a full-fledged comparison between this photo and da Vinci's Last Supper. But I think some art history/pop culture savants might like to engage in some discussion, so I've posted a little about the photo on a "LOST" blog that I share with friends (see here). Feel free to take a gander.
Thanks for sending me this photo, Todd! It made my day. And if anyone does find some strong connections between the "LOST Supper" and da Vinci's Last Supper, please comment. I'd love to know your ideas.
