Reyhan over at The Bay Citizen hips us to the outdoor cardboard xmas tree lot on 24th:

A few weeks ago, I came upon an odd sight on 24th Street: a small Christmas tree lot, on the sidewalk, outside a clothing boutique. The trees were fanned out like any other lot, except there were no green branches. The trees were made of recycled cardboard and cut by machines relying on solar power.

It turned out they were the work of Hanna Sitzer, a local artist and set designer. At the time, she had mentioned that people keep sending her pictures of their fully decorated trees. The one sitting in my living room remains bare, but there's always next year.

Hanna leaves the trees intentionally blank so you can decorate them yourself (like hanging ornaments, only with art supplies that get you high!).  Unfortunately the tree lot is now closed, but you can still run into Wonderland (24th @ Alabama) to snag a tree for yourself.
