I would like to make a simple business lobby sign to place next to the door to my small office and it would be nice to "match" or mimic the font on the door number.  The business center has many small offices and all have this same sign on the doors made of this material and using this font.  I don't have much other information - the sign is a hard plastic or vinyl.  I know the owners would also love to know something about this font - they might wish to match it to other signs, too.  And they have a TON of signs (don't press this button, no bikes upstairs, please close this door when you leave, etc, etc.)

Looks like Optima.

Thank you, Miss Nobody.  That helps.
