What did a Maryland birth certificate look like in 1993?

I have a document that says "This is a birth notice. This is NOT a birth certificate." from the Vitals Record. But my mom says it IS a birth certificate. The document is really small, the size of a small, long envelope. Is what I have a birth certificate or not?|||Ask Obama, He'll tell you to lock it up and hire Law Firms to see no one sees it.
