I noticed that Google Maps started using a special logo treatment this morning:
[1]
The logo is apparently promoting Geography Awareness Week 2007 [2].
Google has done various logos promoting holidays and other special events on the main Google logo for quite a number of years, but I believe this is one of the first ever done on one of their vertical search properties. Unfortunately, the logo doesn’t link to the special event page, and it looks a lot like a roasted turkey — the smallness of it makes it hard to read visually, so I’m betting a lot of Google Maps users won’t have a clue as to what this is signifying.
Update: the Google Lat Long blog mentions [3] their support of Geography Awareness Week.
