I built a plywood form for the mortar pour that would allow reuse if the project turned out to be successful. I used an exacto knife to cut out letters and a silhouette of a man with a hat (This is suppose to be Mark) from a 1/32 inch thick rubber material commonly used by sandblasters to cut images out of stone and wood. This "Signblast Tape" allowed for easy cutting, adherence to the wood form without sticking to the mortar, and reuse if I do the project again.
The quick set mortar was ready to come out of the form in less than an hour. It came out very easily, as I sprayed PAM on the wood form as a divorcing agent prior to pouring. I strengthened the image with a little black permanent ink which permeated into the mortar (so I am hoping it stays visible in the wild for a little while anyway).
Not sure where to put this yet. It'll serve as a classic "Hide-In-Plain" sight (HIPS) letterbox. I envision it nestled away in a remote corner of a public park or behind a bench at a picturesque viewpoint somewhere here in DC. Hopefully no one will bother it.

It's really need to see how you made this. It reminds me of boXer:
