About Us

It all began with a vision. In 1969, Gilbert Bloch, our founder, opened Maryland Stamp and Sign Company in Baltimore. He realized the importance of quality signs and the integral part they play in the way we communicate. Gil knew that a coordinated sign system projects a professional image and creates a smooth functioning environment.
