What is this image?

[Stalin]

Hello, I've noticed a lot of people use this when displaying code, or images to do with their site. I've been searching for it but have no idea what I should really be searching for exactly.

I'm talking about the browser design, not the template that's seated inside of it.
Where do I find this? Or am I supposed to design it myself?

Thanks,
Stalin.

Vector design, it can be made in pure CSS if you're up for it.

Try googling 'Browser Vector Design' or something along those lines.

Alright thanks. I'll look into it more.
