Inspirational Apparel For Entrepreneurs, Is there a good market?

[TEentrepreneur]

Hey fellow entrepreneurs. I have owned a printing company for the past couple of years and am trying to pick more of a niche to focus on. I have always been obsessed with entrepreneurship and so I started printing up a few entrepreneur shirts. The shirts have inspiring quotes on them related to entrepreneurship. For instance, one has a quote by Winston Churchill that says "Never Never Never Give Up". Some say follow your passion or Think Entrepreneurship. I've had quite a few business owner friends buy them, but am looking to market to more people. I got them on my website but haven't sold any online yet. Does anyone think there is a good market out there for selling inspirational clothing to entrepreneurs?
Thanks for your input!
