Hey !
During the last few weeks I spent a lot of time chasing mockups, and flyer mockups aren't the easiest ones to find when it comes to simplicity, and free files. I'm not saying there's no good stuff out there, there are plenty, but mostly for sell, and often on black glossy backgrounds, or with other elements around, like pencils, clipers, etc. And I wanted something more, well, bare ? The result is not ment to be original, just useful.
So here you are with a little simple mockup that contains four different ways of showcasing your artwork. You'll find the file very organized with smart objects and all so that you can easily put your designs and replace the background color in a minute.
I hope you'll like it. Please, feel free to use it as you will as long as you don't resell it the way it is or even modified.
As always, feedback appreciated :)

Edit : I'm sorry if you were among those who downloaded the file which contained a mockup of a business card instead of a flyer mockup, but the link is fixed now. Please, if you encounter another problem, tell me, I'll do what I can to help.
