I submitted my idea called "All Smiles" (putting caricatured or drawings of smiles lips, mustaches, noses, goat-tees or logos on dust masks-the type used in construction or the medical field or just for air pollution protection like they do in big Chinese cities). They wouldn't cash my check.
They told me I had to come up with an idea for a device to put the picture on the mask.
I still think it is a great idea and that next year you will see the product on the market because they stole it from me. If they were honest they would have cashed my check.
