If you want a modern and sleek piece of artwork, go for a black and white abstract art print. You can choose between abstract shapes and textures to create visual interest. For these, I would stick to a simple black large framed art print, keep the focus on the dramatic print. To make the artwork really stand out, hang it on a white or black wall.
For a more classic and traditional look, go for black and white photography. You can find black and white photography in modern or vintage styles. If your space is modern, stick to a simple landscape or object, if you’re space is more eclectic, go for a fun vintage poster. These pieces can be smaller or mid size.
If you’re looking for a conversation starter, hang a large black and white portrait. In terms of art style, I would recommend a simple line art piece if you’re a minimalist, and a watercolour, ink or photograph if your style is more eclectic or maximalist. These bold art prints can really add some drama to your walls. For sizing, I would go for a medium to large framed art print so that the face or figure isn't too small.
