An anonymous story submission pointed this out on Friday:

A picture has appeared on Flickr that purports to be an Apple Special Event invite for February 1st.

The teaser text is "should acquaintance be forgot?"

Could it be for real?

MacScoop should be able to confirm this by Monday.

Among products expected to be announced: iLife and iWork, music announcements (iTunes/iPod).
