All wall based artworks available for sale at Wyecliffe Galleries are sold ready to hang, with the most secure method for the applicable piece; this ranges from string, to D-rings.
We suggest using screws and the correct wall plug rather than picture hooks, and they are more capable of carrying sustained weight. Most good DIY stores will have these for sale and be able to provide advice based on your wall material.
Wyecliffe Galleries can also offer a nationwide installation service; Picture Hanging.
