I don't see a picture.To do a chalkboard cake dust white petal dust over black fondant and rub in. Add vodka to the dust and use a thin paintbrush to letter. It takes practice. Here is my winky first attempt.
That's cute. You could make yourself a stencil for the basic format of the font and then remove the stencil and free form it from there.
Freehand the lettering. Whatthedogate's cake looks much more like a chalkboard than the attached picture.
To make a stencil I would print out what I wanted and then cut out the letters, leaving the rest of the paper intact. You could pin this to your fondant covered cake and then mark the cutout spaces to create the letter. Make sure you remove those pins! But I agree with Sandra that the design you're wanting could be done freehand to great effect. Just start in the center. For example, on the "VINTAGE" I would do the T first and then the N, A, I, G, V, E so that you get the arch just so. Work from the center out.
When I do chalkboard cakes, and I've only done 3 so far lol, I used powdered sugar to give it that "erased" chalkboard look. I also used bright white candy melts, put them in the freezer to harden, broke them in half to create a point, and then used the pointy end to do my writing.
you could also cover the cake with the black fondant and make "chalk" out of white chocolate to write your letters on the cake. As for the white chalk dust ... I would roll the fondant out on 10X sugar and make sure the "sugared" side is on the outside.
