I have a vintage 1960 aluminum tree that we put up a couple of times in the early aughts. When baby Poe turned out to be an eater of the aluminum "needles", we had to keep it put away for his safety and well being. Now that he's gone, we half thought about putting it up this year, but didn't really have a place ready for it because we still like to have a real one. I think we'll plan on it next year. It's about a five-footer, and I've even got the turning base and color wheel.
I bought that tree on eBay back when those were becoming the latest hot retro thing. It's nice that it turned out to be a 1960 one, simply because that's the year we'd just moved to Florida and we had a small silver one for a few years.
