The short answer on availability

Robert Strubin prints in black and white are not available from Auvrique. The catalogue currently carries no editions by this artist in any format, framed or canvas, so there is no monochrome option to point to and no way to order one. Stating this plainly saves a search through pages that will not help.

The question still has a useful answer on its merits. Most reproduction sellers work from color originals, and a black and white print is almost always a grayscale conversion rather than a separate edition. That conversion is a real product decision. It strips the palette the artist chose and replaces it with a tonal range the artist never approved, which matters more for some paintings than others.

What a grayscale conversion actually does

Converting a painting to black and white is not a neutral act. Warm tones and cool tones of similar brightness can collapse into the same gray, flattening depth that depended on color contrast. A landscape with a pale sky and pale water can lose its horizon entirely. Before ordering a monochrome version of any artist's work, it is worth asking whether the composition survives without its palette.

For a minimalist interior, the safer route is often a work that was drawn or printed in monochrome from the start, or a color painting whose palette is already restrained. If Strubin is not a fixed decision, browsing a framed poster edition in a similar quiet register or a cooler landscape such as a winter river scene may get closer to the look than a forced conversion would. Our guide to warm and cool rooms covers how palette reads on a wall.

None of this rules out the conversion route. Some sellers will produce grayscale on request, and the result can be handsome when the original has strong value structure. The honest framing is that a converted print is an interpretation, not a faithful record, and it should be priced and chosen as one.

If a monochrome Strubin is not essential

The underlying need here is usually a quiet, graphic print for a minimalist room, and that need has more than one solution. A work with a narrow tonal range, a strong single subject, or a muted original palette will sit comfortably in a grayscale interior without any conversion at all. The subject guide to Strubin's recognizable motifs explains what his work typically depicts, which helps judge whether it would suit.

Format matters less than tone here, but it is not irrelevant. A framed poster with a thin black frame reinforces the graphic, monochrome feel a minimalist room wants, while canvas softens it. The comparison between canvas and framed poster sets out that trade-off in detail. Whichever route you take, choose the work for how it reads in gray or near gray, not for the name on the signature.
