To use these posters and prints, simply find a nice spot on your wall and hang them up using nails or adhesive strips. Make sure the surface is clean and dry for better adhesion. Avoid hanging them in direct sunlight as it may fade the colors over time. To keep them looking great, you can gently dust them with a soft cloth every now and then. If there are any stains, use a mild cleaner on a damp cloth and gently wipe the affected area. That's it - enjoy your beautiful Wumbo University art!
