An urgent update to this previous post! “Lore & Legends” is now presenting “D&D” both with the small-caps ampersand and the full-size ampersand. Occasionally in the same paragraph.
@scottfgray On the second page, it's using the full height ampersand in running text, but the small caps ampersand in small caps titles. The trouble with that is, you only use small caps ampersands in small caps abbreviations, like if your house style is to write "AT&T" in small caps. If you're using normal, full height caps for the A and the T's, the ampersand has to be full height, too.
@scottfgray As for the first page, I wonder whether they originally had "Dungeons & Dragons" spelled out in both instances on that page, small capped as they like to do, and someone find/replaced them to "D&D" without changing the style.
