Altered postcard art

I came across a mail art call "Send Me Flowers" linked to the Mail Art Forum and thought it would be a good excuse to alter this vintage postcard I picked up at a neighborhood antique shop quite a while ago. It appears that the man is standing in a field of dahlias, so I drew a dahlia on it with a brown fine point Stabilo pen, then added the green leaf color with a Pitt brush tip pen and colored the blossoms with Cretacolor pencils. The pen at first seemed not to take very well, so I deglossed the surface with fine sandpaper, which scratched it up a bit, but that looks OK to me.
