Creating 3D text from 2D image texture?

I have no idea if this is possible or not, but I was wondering if there is any way to create 3D text from a 2D image?
Basically, what I want to do is turn this image: http://billrudloff.com/DoorSign.pdf (PDF technically, I know)
I want to turn it into this: http://i.snag.gy/7GWc8.jpg

Is that possible? The font is listed as N/A so manually recreating it isn’t much of an option.

Thanks

It gives you the approximate fonts to use on that page.
