You are looking at a Mint Condition Hallmark School Days Promo Pamphlet from 1999.
The Promo Pamphlet was produced to generate interest in their cool 1999 School Days Lunch Boxes series of collectibles.
It is printed on glossy stock and measures approximately 4 1/8" x 8 1/4".
It will ship bagged, boarded and sandwiched between 2 pieces of cardboard in a mailer with Tracking in Canada and the US.
Cheers.
