Suddenly, there has been an infiltration of 'Caricature Phonies' that sell their 'so called' works on the internet. Beware... they are software programs that take your photo and manipulate it with putty and warping designs, (actually anyone can do it via the free software), but they will sell it to you at an exorbitant price.
It's easy to spot, as all of their sample caricatures have the exact same style and texture.
Please don't be fooled! Artists like myself, put a lot of work, i.e. thinking, and skills into drawing a caricature. One that will produce smiles, if not chuckles, for a long, long time.
