For the past 20 years, creator of DI and senior author of the DI programs Zig Engelmann, has produced a calendar featuring a sampling of his watercolor paintings to give to his friends and associates. This year, to celebrate that 20 year landmark, he is making the calendar available to you! Each month features one of his paintings, taken from scenes primarily in Oregon. When asked about his paintings, Zig says, "I try and make them as realistic as possible. I want people to look at them and be able to feel like they are really there."

Copies of the calendar are only $23.95 each, which includes postage. Click here to order your copy.
