Last weekend I picked up a brochure at one of the rest stops on the oHIo Turnpike, entitled "Guide to Quality Ohio Wineries." (I looked for a corresponding "Guide to Shite Ohio Wineries," but did not find one.) Ohio Grape Industries shelled out nearly $14,000 for 39,000 of these full-color, 56-glossy-paged brochures. So I'm wondering why they didn't hire a quality designer to promote their quality wineries.
This is in no way intended to rip on the designer of the piece. It's evident that she/he made a good effort, and there are some really nice touches to the brochure. The color palette is pleasing, the images are inviting and match the Web site, and the maps are clear, concise, and consistent. However, there are indications that perhaps this person has not designed many brochures.

1) I'd like more space between the headline and the copy, but the contrast between typefaces clearly shows the hierarchy of information. Good.
2) Font choice. In the designer's favor, it's not Papyrus, Comic Sans, or Times New Roman. Unfortunately, it
is Avant Garde, and it looks like a condensed style to boot. It's not the most readable typeface for long blocks of text, and it's a little out of fashion, but it's not offensive. One note: the "1" needs to be kerned closer to the other digits for the years.
3) Only one space is needed after a period. The computer is not a typewriter. Type isn't monospaced any more. The first thing I do when I get copy from my boss is to run a "Find-and-Replace" to change all the double spaces to single spaces. She's never noticed.
4) Left-aligned text creates a ragged edge on the right; it's just a fact of typography that needs to be dealt with. An inconsistent line length can make distracting shapes and draw attention to the rag. Balanced line lengths render the rag nearly invisible to the reader and smoothes the way to the next line of text. Anything that helps the reader get to the information more easily is good.
5) Odd-numbered pages are never, ever on the left.
That last one makes my eyelid twitch.
Bring it on, typography hatahs!
