On BoingBoing, someone sent in this photo of an AT&T store in downtown Manhattan:
"Perhaps it'll be available last year," Mark Frauenfelder wryly notes. Commenters chime in with their own time-travel jokes, and a couple point out the added typo of "out stock" for "out of stock." One commenter wonders if the photo's a fake, but I'm quite sure it isn't. Substituting temporally for temporarily is a common error, perhaps due to the phonological process of haplology (the omission of one of a pair of similar sounding syllables, like saying lib'ry for library). [Or, as Andrea conjectures in the comments, it could be yet another result of the Cupertino effect.] It's so common that a quick search on Google Images and Flickr turned up a dozen more photos of signs with temporally. There are so many that it's probably just a matter of time before there's a whole blog dedicated to such signs, in the style of other peeveblogging we've seen (apostrophe abuse, unnecessary quotation marks, lowercase L, etc.). A gallery follows below.
