What do you have in mind for the style and theme of the business card?
Card will be square
On very thick stock (min 350g), so that stamping treatment is not "felt" on reverse side
Embossed side in either very pale green or Tiffany blue
Information side white, lettering in same color as front side.
Serif font in either: Cochin, Superclarendon, Orya MN, American Typewriter or Rockwell or...something else.
Same font on front and back.
Icons instead of words on back of card (twitter, email, mobile...)
Overall feels needs to be elegant and calm
Brand name to include on the business card
What to avoid
no drawings, images, illustrations.
Nothing coy, cute, childish; target audience is senior executives
