Cover the marks on the letter, the card, and the envelope. What remains should still be one house: the same rail, the same type, and the same quiet device. If the three agree only when the logos show, they share a badge and nothing else. Design that rhyme first. The mark may claim it afterwards.
Finished alone, the pieces drift apart. The letter centres itself under a bar, the card sits flush right with a stripe, and the envelope starts further in under its own line. The other plate covers every mark with a flat rectangle. The three still share a left rail, one type setting, and one vermilion tick, so the suite can be judged without the logo.
How to check it
- Cover every mark with paper or a flat rectangle. Ask someone who has not seen the logo which pieces belong together. If they cannot say, the suite is the logo.
- Check where the type starts on all three. It should fall on one rail. A centred card, a right-aligned letter, and an indented envelope will not survive the cover.
- Count the accents. One quiet device, repeated at the same size and the same distance from the rail, is the system. A bar, a side stripe, and an underline are three systems.
