I believe it is the author of the Python Requests library, and I believe this is the logo in question: <a href="https://upload.wikimedia.org/wikipedia/commons/a/aa/Requests_Python_Logo.png" rel="nofollow">https://upload.wikimedia.org/wikipedia/commons/a/aa/Requests...</a>
Can someone provide some context? It looks like this is a Python developer for Heroku who sold his stake in something and has the logo on his arm? Which logo?
