Other billboard examples
Messages on the sign can be changed periodically or they can be static depending on the needs of the customer. In recent years a 'vinyl wrap' has been used on many structures for easy maintenance and message rotation to target specific viewing areas.
Many Billboards are owned by advertising companies who lease space to individuals or businesses. Length of leases are determined on an individual basis. Cut-outs and extensions are sometimes used for greater effect.
Individuals or small businesses can own billboards as well. Permits must be secured from the Iowa Department of Transportation prior to erecting the sign. Site leases, sign fabrication and construction would be the individual's responsibility.
