Instructor magazine, which has had various names throughout the years, originally began publication in 1891. The magazine focuses on teacher-related topics and curriculum ideas, and as of 1990 is owned by Scholastic. This listing is for a March 1981 wall calendar/lamb poster that was a supplement in that month's issue of The Instructor magazine. The calendar features wonderful color illustrations, including Spock from the Star Trek franchise! The art is signed by John R. Jones. Additionally, each day on the calendar contains an interesting bit of info for the teacher to share with their class. This is double-sided and the reverse shows a photo of a lamb with daffodils and includes a short paragraph of lamb facts. This poster measures approximately 21 inches wide and 15 inches tall. It has been laminated. There are some old rubs to the paper that happened prior to lamination. Will be shipped rolled in a heavy-duty tube.
