For anyone getting a stamp, the Code of Maryland Regulations, Title 09, Subtitle 23 states:
B. A licensee's seal shall be a seal consisting of the pictorial device of the Great Seal of Maryland as a center, surrounded by the words "State of Maryland" and "Professional Engineer" and the licensee's name and license number.
I know people were wondering whether to put 'Licensed' or 'Registered' Professional Engineer. Don't put either!
