I do indeed have an LBT shirt, yep, yep, yep. It was custom-designed and I ordered it online.
I was pleased with how the image turned out, although the shirt itself is a bit too large for me. So I might order another shirt sometime with the same image, but a smaller size.
I got some positive comments on it from my mom and brother (who both already know I'm an LBT fan). I also wore it to book club recently and one of my friends at book club commented favorably on it. This one elderly lady I'm friends with also commented on it, but she has no familiarity with LBT so she didn't know what the image was about. I was also hanging out at my local university one afternoon, and this little girl passed by and she seemed to be staring curiously at my shirt, although I'm not sure if it's because she actually recognized The Land Before Time or not. Those were the only instances where it was obvious someone noticed, although it's a new shirt and I've only worn it a few times so far.
It's a weird feeling. Like, I don't think adults enjoying children's media is a bad thing at all (in fact I think it's good). And I'm happy with the shirt itself and my passion for LBT makes me want to wear it. And yet, I've still felt a little sheepish when I do wear it. :/
