This is a business card holder I made for my booth at the Spectrum Live show. It is made out of pine from an old door I garbage picked. The bow and locking bar are bed spring wire from a discarded bed spring. The pedal is scrap plastic and the spring is old wound up electric wire. I luckily had access to a laser cutter for the lettering which I did in Adobe Illustrator.
I ended up putting some loose cards next to the holder after noticing some peoples apprehension.
