combining two objects into one

Here is my situation: I have a logo with letters of black color and a background of a white. black on white. How do I make it as one object. I want the logo to appear and disappear without having to select the letters and background individually. I want the logo and letters to disappear together. I tried parenting them (unless I am doing something wrong in parenting them). If I make the letters parent to the background I should be able to select the background to make the letters disappear without having to also select the letters.
