Put the eggs in a casserole, and boil the hard. Take them aside and pour cold water in the casserole and let them cool down.
Butter the bread slices lightly, use the same butter that you have at home for normal sandwiches/breads.
Wash the salads leafs in water and add them on the bread with the top of the salads leafs toward the edges of the breads.
Put some mayonnaise evenly on the salads leafs, don´t use to much, otherwise it will mostly taste mayonnaise.
Peel the eggs and dived them with a egg slicer or with a knife in thin slices, then place them evenly on the breads. If you make two big bread slices instead of four small ones, use two eggs per bread.
Peel the shrimps if you use fresh ones, and dived the shrimps evenly on top of the egg on the bread, make them look like a mountain in the shape, it is more impressive when serving them.
Cut the lemon and the cucumber in thin slices and make a cut in the middle almost right through it. Bend them where you made the cut on two different sides and place them on top of the bread as decoration.
Place the sandwiches in the fridge until it is time to serve. When eating them you can squeeze some lemon juice from the lemon on top of the shrimps for adding some extra taste.
