We made this mouse house advertising pop up card for BLP entreprenad. BLP is a company that works with technical service/maintenance of heat and smoke vents but also with fire sealing and with the legally regulated maintenance of air-raid shelter rooms. The card was sent out to their customers (public and private real estate companies) together with a customer survey/inquiry.
The mouse asks for your help to open the heat and smoke vents. When you push the red parts with smoke vent symbols at the bottom of the house one of the vents are opened and tells you it has been maintained by BLP entreprenad. The other vent can not be opened enough and it says the reason is lack of professional technical support. The card was printed at Digaloo, the best high quality printing company in Stockholm.
