However, Wittgenstein claimed that pictures cannot represent their "own" logical form, they cannot "say" what they have in common with reality but can only "show" it (TLP 4.12-4.121). If representation consist in depicting an arrangement of elements in logical space, then logical space itself can't be depicted since it is itself not an arrangement of "anything"; rather logical form is a feature of an arrangement of objects and thus it can be properly expressed (that is depicted) in language by an analogous arrangement of the relevant signs in sentences (which contain the same possibilities of combination as prescribed by logical syntax), hence logical form can only be shown by presenting the logical relations between different sentences.
