Manga Boy Supplement Promotional Poster - Vintage - Astro Boy - Rare - Excellent Condition

Item/Type: Poster. This is a supplementary poster from the manga "Shonen" (Boy), dating back over 40 years. I purchased it at a charity auction and displayed it in a frame. Initially, I thought it was a reproduction, but the seller confirmed it was from the original period, which surprised me. Upon closer inspection, it was indeed a genuine supplement from "Shonen." However, my collection has grown too large, and I'm downsizing. Therefore, I'm putting it up for sale. I will ship it framed. Dimensions are approximately: Height 48cm, Width 28cm. These are approximate measurements. Please use them as a guide. The price reflects what I paid for it at the time. Thank you.
