The $9 t-shirt deal of the day over at Teefury today is Battlestar Galactica-inspired “So Say We Can Do Itl” shirt, by artist Bregan1989.

The sale at Teefury began at midnight EST (Monday, January 10, 2011) and will continue for 24 hours from then, and once it’s over, it’s gone from the site for good.

The design is actually a mash-up of the revamped Battlestar Galactica and the popular “Rosie The Riveter” poster, with the Starbuck character (played on the series by Katee Sackhoff) in the Rosie stance. The saying on the shirt is “So Say We All,” which is the credo of BSG (the Rosie poster’s motto was “We Can Do It!” so the shirt’s name is a mash-up of the two sayings).
