In terms of hanging your art - we have installed D-rings and wire on the back of your painting to support your piece. To hang it on the wall, you can use heavy-duty art hooks or screws which can be found at your local hardware store or Amazon. Ideally, ones that can hold 50-100 lbs of weight. To be extra safe and spread out the weight, we suggest using 2 points of anchor for hanging. 

Otherwise, you can even use 2 screws into studs. If a stud isn't available, you can also use a drywall anchor. We don't suggest drywall anchor hanging for pieces larger than 48 x 60". 

For cleaning and maintaining your framed artwork from dust, we suggest lightly wiping it with a cotton cloth. Never use cleaning solutions on the artwork or frame as this will cause damage.
