I was doing a little checking around to see what the Cinelli 1A looks like and ran across this link...
http://www.bikepro.com/products/stems/cinelli-road.html

The 1A is plain without a logo, but, look closely at the auction. The stem in the photo is an XA, and the XA's do have a logo! So, no telling what you're getting Lisa.

Edit: After looking at the link I provided above, it's obvious the auction is for a 1A in an XA box. Oh well.
