The hearts can be customised for many anniversaries:
The first anniversary = paper (as pictured)
The 25th anniversary = silver (either silver backing paper or the red heart replaced with a silver)
The 40th anniversary = ruby (as pictured)
The 45th anniversary = sapphire (red heart replaced with a blue heart)
The 50th anniversary = gold (red heart replaced with a gold heart)
The 55th anniversary = emerald (red heart replaced with a green heart)
Each white paper and the single textured card red heart measures about 2cm and stands away from the dove grey pearlised backing. The 3D effect adds depth to this simple design.
This is then mounted into a white wooden frame that measures 8x8 inches (20x20cm) externally. There is a hook on the reverse of the frame for wall mounting.
Also available with a white pearlised backing: convo me and I will set up a custom listing.
It would look like the 9 heart picture:
