DRG = Digital Raster Graphic. It's a generic term, often used to indicate
scanned paper maps. Nothing special about them. Usually 8-bit color
images with georeferencing (TIFF World = affine parameters).
Most likely, you don't "see" the raster because your region settings don't
match/encompass the imported raster.
g.region rast=<your drg>
