This is vintage calendar from England, a 1989 Tesco ( Grocery Store), Healthy Reading Calendar.
Produced in conjunction with Penguin and Puffin books as an advertisement for the books and the store.
Unused and unmarked, very clean, a folding section type, all one piece as you will see from the pictures.
Folded, measures 7.5\" x 5.5\" unfolded measures, 36\" x 5.5\"
Something a little different for a collector.
This has been boxed and stored for many years, I just discovered it today when I was unpacking a box from 25 years ago. I cannot remember now but I feel that it would have been a promo gift at the time.
Thanks for your interest, I will ship worldwide.
