What are the key considerations when choosing a 'Marvel Comics All Characters' poster?

Consider the size of the poster relative to your space, the printing quality (look for high resolution and vibrant colors), the style (e.g., classic comic book cover style, minimalist character silhouettes, or a dynamic action scene), and whether you want a chronological listing, a thematic grouping, or a purely alphabetical arrangement. Also, check if it includes characters from all eras of Marvel Comics, including recent additions.
