At Dirk's suggestion, I contacted Joel Hollingsworth at Gameday Depot in Kingsport with a question: Is it possible to add my OtF monicker to the back side of an OtF teeshirt?
Joel's answer is: Yes.
Go the Design Studio at the SB Nation store: http://custom.gamedaydepot.com/sbnation/Design Studio.
From the left side palette, select Products. Then click on Teeshirts. You'll find choices including Junior Tees, Ladies Tees, Long Sleeve Tees, Pocket Tees, Short Sleeve Tees, Organic Tees, Sleeveless and Tank Tees.
From the right side palette, choose your Color.
Now look again at the left side menu and choose Clip Art. Select SBN Hockey. From the listed logos choose On the Forecheck.
You've completed the front of your shirt.
Now look at the menu on the right side and click Back. Click the Names and Numbers panel. Type in your name (and a number, if you'd like) and click Save.
Upload your image and place your order.
You'll look great. And when you're at the Bridge and you spot the guy wearing an OtF tee shirt and an Ohio State cap, you'll just have to wait until he turns around to see that it's...CISAR.
