I actually struggled with this one, even though there are a billion things that start with the letter B.
And then I cheated.
B is for Ball.
Program used: Photoshop CC 2015.5
Cheat used: created ball using ellipse tool. Freehand drawing is for losers.
More cheating: used the Lighting Effects filter to create a pseudo-3D effect
In other words, I used about the least amount of my own minimal artistic talent as possible. I’m okay with that because I dig the totally retro border and Cooper Black font. Also, you can see the pixels on the ball because I was too lazy to figure out how to apply antialiasing. That makes it more retro.
