While some creativity is good, I tend to find the oddly shaped or sized cards annoying and end up losing and/or tossing them. Also, make sure "creative" doesn't equal "hard to read" or "lacking essential info."

Sorry to pop in my two cents, but I've received way too many business cards that someone obviously put a lot of effort into, hoping to stand out to clients, but instead, they unintentionally sabotaged themselves.

some of those are pretty hot.
But I'm a fan of kitsch so I guess that isn't saying much realistically.

I like the ones with the creative impressions (the dentist with teeth, the Elkha one with the tree) and the cute edge detail on the Darling House card. I feel like those touches add flair without distracting from the information on the card and without making the card difficult to store in your typical business-card holder.

I think many of these are probably design projects. Graphic designers do really unique stuff like this from time to time to push their own creativity, not necessarily in earnest. It helps keep them fresh and looking at objects in new ways. Just as for instance, though, I'd never go to a divorce lawyer whose card tore in half... it'd be too weird!

Thanks for sharing!
There are some pretty interesting ideas in there.
