I would think that it depends on the jurisdiction where you live. These days, selling to a minor is a big deal. If it is not a felony in your state/city/county, then you might get the max penalty for the misdemeanor. Don't do it again! My son used to clerk in a liquor store when he was in college. The cops were constantly dropping off underage folks to try to buy liquor.

An engraving is a print that was made using an engraved printing plate. In printing, to engrave means to carve a pattern in a printing plate. The earliest known dated engraving is from 1446, so the technique is at least 560 years old. The basic process is to engrave the image on a metal plate, apply ink to the plate, wipe it so the ink only remains in the engraved lines, then press it onto paper to produce a print of the image.
