Are you looking for extended package with T-shirt mockup? This one is just for you. It offers you 3 in 1. You pay once and get 3 set, , i.e. a total of 24 PSD files in the highest resolution 4000x4000px, 300dpi.
The package includes two scenes at a resolution of 4000 px with the most used views from the front and from the perspective. It has a black leather texture with a golden stamp effect.
Categories, unlike tags, can have a hierarchy. You might have a Jazz category, and under that have children categories for Bebop and Big Band. Totally optional.
