These historical items are great for collectors or as decorative pieces. If you're using them for display, you can hang the color picture or the matted plate on your wall. The children's book can be placed on a bookshelf to add a touch of nostalgia. The playbill can be framed for a more elegant look. When handling these items, be gentle as they are old and may be fragile. To maintain them, keep them away from direct sunlight to prevent fading, and store them in a dry place to avoid mold or damage from moisture. Don't try to clean the children's book aggressively as it may further damage the pages. For the playbill and picture, a soft, dry cloth can be used to gently remove dust.
