Here's another new one. In preparing for an upcoming writers' conference (my first), I found out that industry standards for writers are different than every other line of work I've ever been in, and this includes business cards.
Everything I've ever learned about business cards has always involved the admonition to never put your picture on a business card, often accompanied by the statement, "Only realtors do that." (I still don't understand why realtors do it, either. Can anyone explain that to me?)
In the corporate world, to have your picture on business documentation (including business cards and letterhead) is a serious infraction. It's illegal to consider someone's appearance as part of the hiring practice in many industries, and corporate lawyers frown on things that might incur an EEOC investigation or lawsuit. Most HR departments in those industries have strict policies that specify that any resume or c.v. submitted with a photograph gets automatically destroyed and removed from consideration. Apparently writing falls outside of the general practice guidelines I've been taught to observe.
I'm trying really hard not to cringe as I attempt to design my new business card with my picture on it. My muscles are revolting against me, tightness is locking down on my spine, attempting to paralyze my fingers' attempts at adding the picture. Yikes.
