Light shadow from all sides of the object!

Hello,
i need help creating a shadow from all sides, so that the broshure can be rendered with shadow catcher. it has to be placed on white background and has a white line of top of it.

The Problem: basicaly i tried everything every position of the light but i cant get shadow from all sides so that the top side doest merge with the background :((

The broshure itself is hidding the shadow, like the example below, just another scale.
You can use another object to fake a shadow for the broshure.
Maybe you can try to increase ambient occlusion shadow.

hidden_shadow

i’d suggest to place the shadowcatcher lower so there is some space between it and the magazine
