Put one person in front of it
Seventies sci-fi covers sold awe rather than plot, and they did it with a single trick — a tiny human silhouette placed in front of something enormous. Everything else is decoration.

A ringed planet fills most of the shirt. At the bottom, about two centimetres tall, is a person standing with their back to us.
Remove that figure and the image is a nice picture of a planet. Keep it and the planet becomes enormous, which is the entire emotional content of the genre.
Why does the figure matter so much?
Because scale doesn't exist in a picture without a reference.
The eye has no way to judge how big a painted sphere is. Put a human silhouette in front of it and the comparison is instant and involuntary — and the feeling produced is awe rather than information.
That's the same mechanism kaiju art runs on, pointed at wonder instead of threat. Helicopters make a monster frightening; a lone figure makes a planet sublime.
What are the components?
Five, and the palette is doing a lot of the era's work.
- A vast object — planet, ring, arch, structure, ship — occupying most of the frame.
- One small silhouetted figure, usually from behind, usually not centred.
- Flat airbrushed forms with soft gradients and almost no texture.
- A restricted palette: two or three colours, often a warm object against a cool sky.
- A letterspaced title in a serif or a wide sans, set small and calm.
The calm typography is the tell. This tradition never shouts — unlike the horror covers of the same decade, which were competing in an aisle rather than on a shelf.
Can I use a real book's cover?
The paintings are the artists' work and the titles belong to their authors, so no.
The visual language is common property and always was — these artists were working in a shared idiom, and the same three or four compositional moves appear across hundreds of covers by dozens of illustrators.
Inventing the book is also the enjoyable part. A title, an author name, a fictional imprint, and you have an object that looks like it came from a specific 1974 that never happened.
What makes a good invented title?
Quiet and slightly wrong. Two or three words.
THE LONG QUIET. SECOND SUMMER. ALL THE WAY DOWN. The era's titles were understated in a way
modern ones aren't, and that restraint is what makes them read as period rather than as pastiche.
Avoid anything that sounds like a franchise. The moment a title sounds like it has sequels, it stops sounding like 1974.
Should there be an author name?
A small one, and it's the detail that convinces.
Set beneath the title at half the size, letterspaced, it does what a figure number does on a technical diagram — implies a whole apparatus of publishing that never existed. Add a fictional imprint and it's complete.
The same trick as a model designation on a parts diagram: one small piece of bureaucratic detail makes the whole thing feel found.
Does it print well?
Very — it's flat colour and a strong silhouette, which is close to ideal.
The airbrushed gradient across the large object is exactly the case where gradients are fine: big, soft, and not carrying the structure. The structure is the silhouette of the figure and the edge of the planet, both hard.
Gradient as atmosphere works; gradient as edge doesn't.
How do I get one made?
Describe the vast thing at JustOG, the title, and where the figure stands. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
Designs other people have published are in the shop.
The planet isn't big. The person in front of it is small.
