Oh Cool! Love the etch and the fact that it is probably unused. Yeah, attics and crawlspaces are good places to find treasures!

Yeah attics, crawl spaces, and cellars / basements can house nice some vintage stuff. The attic this bulb came from is the same place the Philips 100 watt in the next picture came from. There are also many other bulbs up there, but all the ones I've seen are burned out or broken. There may be others buried under junk up there, though!
