I have a question that has been stuck in my head for a quite a long time. Let's say, I designed a business card for my client and would like to publish the design to my portfolio. Because the business card has my client's identity (name, phone number, email, etc), is it okay if I publish the design while hiding my client's identity?
Just use a dummy name and contact info. The actual name, title, phone, etc., are not important. It's the type usage and placement which will convey the overall design.

That being posted..... if there's a logo, well, you can't really "hide" the identity of a logo. And removing a logo from something like a business card can cause the design to completely fall apart.
So, leave the branding, but replace any personal information or contact information.
