Online artist Vegan Sidekick has launched a clothing line which includes T-shirts, vests, and tote bags.
The artist - whose real name is Richard Watts - revealed the news on his Instagram feed.
Admitting it had taken him four years to put together, he asked fans for feedback on the designs.
He wrote: "I hope that you will find something that you like, and if not, please let me know what you are looking for, because I can add more designs over time and I want people to have what they want.
"I searched for a long time for an online company that was ethical, and could also print on demand and handle shipping.
"The garments are made by Rapanui, and everyone I have spoken to has been happy with them. The same company handles the Vegan Society's clothing."
Vegan Sidekick - who has nearly 140,000 followers on Instagram - is best known for his humorous comics, which highlight the absurdity of anti-vegan arguments.
Speaking to The Vegan Society about his trademark style, he said: "I think that including humor in my work makes people want to share it. So non-vegans end up seeing my comics and reading them before they know what they’re getting into.
"I wouldn't say that my approach is the only one that works or should exist, or that I get it right every time. I'm not a perfect advocate – I screw up, either in the comics or how I speak to people. There are some people who criticise or even hate what I’m doing, and that’s alright."
