ETC pioneered the use and combination of black and white photography with full color pictures to point out individual parts of a whole. Similar to our elementary "parts of..." cards, here too we have implemented the use of this technique that has now become the accepted standard. Each part of the flower is isolated in full color while the rest of the parts are faded in gray. A full photo is included as a key reference so that students and teachers have access to the full look of the object in its realistic colors. 21 cards showing 7 different parts plus a key card in the standard sizes indicated below for a total of 24 cards. Regardless of the finish you purchase each card is individually cut with rounded corners.
