In my condo, one of my favorite kitchen art buys was my knife and fork sticker decal. For under $30 bucks it was a perfect something to take up space on the door to my air conditioner. I always thought that it would be fun to decorate my office with these, since I obviously can't paint or even in some cases haven't been able to hang art in some office buildings.
While looking around for office decals, I found quite a few different options. The colorful frames below would be fun, especially with random family pics or places you want to travel inside. I bet you could just print pictures on regular printing paper using a color printer to frame. I also love the headboard-wonder if it would be cute for a temporary fix if you are in between headboards, like I usually am! The grandfather clock isn't my home style but it looks great in the office as shown. And, who doesn't need a chalkboard decal? That could go in a kitchen, by the front door, for brainstorming ideas at the office...you name it!
