Physical Review journals used to indicate Editors' Suggestions with this sign:

Physical Review Editors’ Suggestion icon

In an editorial announcement they state that:

The icon contains the printer’s mark that at one time appeared on the covers of all sections of the Physical Review.

I'm wondering: where did this sign come from? Does it have any meaning?

It looks just like, well, a printer's mark, in this case, a fleuron: ❦ . I don't think there is any particular meaning besides aesthetics.

  • It is indeed a fleuron, specifically a floral heart bullet. I can't find the Unicode for an 'upright' version, but ignoring rotation these seem closer matches: ☙ ❧

A quick search found:

Printing single vine leaves originated around 1505. It does not mean anything. Around 1530 they were extremely popular with printers. Printing a single vine leaf in 1530 was like printing a cat picture in 2010.
