At first glance, you might have trouble figuring out why Marvel's Mighty Thor, Iron Man, and Captain America are all together on the same greyscale 100% cotton Marvel Pillars of Strength White T-Shirt. Then there it pops into your head - they all started out 'weak' or handicapped in some way! Think about it...Tony Stark started out with a bum heart, Steve Rogers was a little on the scrawny side, and Donald Blake was slightly infirm! BAM! That being said, the Marvel Pillars of Strength White T-Shirt is a testament to the combined will of these three powerhouses!
