B4 “Speed” Posters — Original Japanese Slim Vertical Posters (c. 25 × 73 cm)
Japanese “Speed” posters are a striking slim vertical format—roughly 25 × 73 cm (size can vary slightly). Designed for quick display in cinemas and shops, they were produced in far smaller quantities than standard B2 posters and were frequently taped or pasted up, making surviving examples increasingly scarce. A highly collectible, space-friendly format with serious visual impact.
