Questal is an intriguing unicase serif.
The face appears rather eccentric, yet it still retains a refined character. The typeface is wider than most, but not to the degree that Aviano is extended. The font includes some interesting OpenType alternate characters to extend the quirky quality of the letterforms even further.
If unicase isn't your thing, the Questal family also includes a small caps variant for more traditional uses. Use Questal for eye-catching and distinctive logotypes or headlines.
