The “KEEP CALM” phrases and posters are very popular nowadays so I added it to this creative sign for OPEN HOUSE that will surely catch the attention of everyone. This creative sign is so simple yet clear and sturdy. The message is clearly disseminated and the OPEN HOUSE logo is obviously seen. I suggest the use of plastic and aluminum material for water resistance and also light to carry. I also suggest the use of lighting effect so that it can also be seen at night. Thank You! 🙂
