This glossy black and white set consists of 30 sketches of dinosaurs plus an un-numbered title card which is inlayed with silver foil.  There are 15 different prehistoric animals  included in this set, each of which has a portrait and a full body sketch.  The cards are numbered with "A" and "B" extensions behind each number (see checklist).  The "A" cards are portrait sketches, have the animals name on a black background, and provide general information on the reverse (e.g., size, time of existence, where found).  The "B" cards are the full body sketches, have the animals name on a white background, and provide descriptive information about the appearance of the animal (e.g., the shape of the hands, teeth, and other physical characteristics).  A credit on the title/checklist card cites "by Eugenia and Paco with Mark Paniccia".  I am uncertain who are Eugenia and Paco; perhaps the artists.  I believe Mark Paniccia is a comic book creator & editor.
