Email, photo reply, reblog or tweet (#obsoletecostume) a pic of old tech-inspired Halloween costumes for a chance to win a signed copy of Obsolete and an accompanying care package of obsolete gewgaws (delivered by USPS! Old school!).

Here are some of my previously-posted faves:

Portable cell phone booth.

Polaroid head, photographed by Polaroid, of course.

Trench coat? Check. Vintage boombox? Check. Only thing is that mine is pink… (via Lindsayism)

I spotted this one at the Halloween Parade in New Paltz, NY. They were “Duct Tape.” Get it?

Another approach to the Polaroid costume.

Nothing like a good data-storage disguise.

What’s with all the floppy disk nostalgia? I guess they’re becoming kind of nouveau pop-art icons—hello, cassette tapes!—but I admit that I don’t really get it. And, um, weren’t they square? Feels wrong to let the iPhone dictate the shape of the floppy. Even if this is an iPhone case. The floppy came first!
