I received this at a movie theater in Hong Kong. Approximately 29.7 cm x approximately 42 cm. It's about A3 size. I will fold it in half and put it in a plastic bag. I will insert packing material in between and ship it via anonymous Rakuraku Mercari delivery, taking care to prevent it from being folded. #SlamDunk #Poster #Movie #THEFIRSTSLAMDUNK
