Each proposes something different about what the firm is. Open any one full-screen to judge it properly — the thumbnails below are live pages, not images.
The firm as a document. Lockup top-left, heavy rule, contact tucked beneath — the head of a page in a manual. Closest to what is live. Keeps the identity in service of drawings and invoices.
The firm as a territory. Full Dunnet flood, everything reversed — the card-back logic applied to the whole surface. The only one memorable from across a room, and the only one that makes the blue the subject.
The firm as a monument. Mark at 240px, contact banished to the corners. Raises the stakes on the mark considerably — at this size it either holds or it does not.
The firm as a filed record. Reference code, dated footer, contact as labelled fields. The most 1970s and the most undercover — the page performs the anonymity rather than describing it.
A 1970s manual cover does exactly this: the plate is the subject, but the page still carries its reference number and issue. The apparatus frames the monument rather than replacing it. Three balances.
Apparatus reduced to two strips. Reference above, contact below, the plate floating between them. The lightest touch — the record is present but never competes.
Both, in full. Plate at the head, filed fields beneath. The only one that keeps H4's labelled rows — and the only one where BY CORRESPONDENCE ONLY survives, which is the sentence doing the most work.
All three ideas at once. H3's scale, H4's apparatus, H2's flood. The mark reversed at 240px is the most arresting thing in the set — and the void reads as a cut in the blue rather than a shape on it.
