I am one hundred percent sure you will at least fall for one of these mockup scenes after examining them. There are three realistic, inviting, and beautiful retro settings. All of them are in an outdoor environment. One is a shutter door of a house garage with a bike and a little garden in front of it. The second one is a vintage wooden board with the sky and green fields in the background.
The last one is a metallic fence in the street with a parked car on its left side. You can use all these settings in both landscape and square positions. If you want vintage results, use this file to present your prepared graphics of all types.
