If you get caught by HYDRA while wearing SHIELD White Symbol on Black T-Shirt we will disavow any knowledge of your agent status or mission. Don't worry though - we are still sending in some heroes and people to rescue you! That's just what we have to tell the press and/or other governments, you know? Totally great for any fan of Marvel's supranational organization, the SHIELD White Symbol on Black T-Shirt is almost as good as Level 7 Clearance. Almost.
