"Postcard Portables did a fantastic job with our public service sign for the non profit SOS Trees Coalition. It was printed and out on the street very quickly. They returned our calls when we had questions and were were great to work with. We wanted our sign moved to various locations in the city and they had that done as soon as it was requested. Having the portable aspect made advertising in different locations a breeze. I would definitely recommend them and our organization will be using them again next year."
