This two-sided poster provides a great value! Affix individual student photos and write in student name and/or birth date. For larger classes, group students by birthday month and creatively photograph them holding signs or standing under labels with their birth dates, then affix the group shots to poster. Even easier, just add a cell phone generated 'sticker' with birthdates to the images, using your favourite photo app prior to printing out student pics. Measures 17” x 22” (43.2 x 55.9 cm). 1 poster/2-sided printing.
