Card Into Frame by 7 Magic
Magician shows an empty photo frame and asks a participant to select and sign a card.
The selection is returned to the deck, shuffled, and then the cards are sprung at the frame. When the cards finish falling, the signed card appears inside the frame!
The back cover is opened to show the card definitely has penetrated solid glass in order to appear inside the frame.
No complicated techniques are needed.
The audience can check the frame before and after the performance to see there is a solid glass.
Frame set, gimmick, and instructional video are included.
