Screenprint in colours on paper. Unsigned, stamped by artist’s estate. Hand-numbered with Banksy’s stamp.

This monochrome unsigned variant of Banksy's Trolleys presents the artist's critique of consumerism rendered entirely in black and white, concentrating the work's conceptual force through the elimination of colour. The silhouetted hunter-gatherer figures pushing supermarket trolleys across the composition retain all the philosophical weight of the original colour version, but stripped of its sepia archæological tonality, the work reads with even greater starkness and universality. The black-and-white palette paradoxically extends the association with prehistoric cave painting — by removing colour, Banksy returns his work to the visual language of the most ancient human art, pure line and shadow on pigmented surface. The unsigned status and Pest Control stamp confirm this as an authenticated edition work from the height of Banksy's productivity, produced in a run of 500 impressions. The loss of the artist's hand-signature becomes conceptually significant: it increases the work's accessibility to collectors who prefer to own authenticated prints without hand-signatures, and it emphasises the reproducibility and mechanical nature of the screenprint process itself. The Trolleys composition, in any format, speaks to the colonisation of all human behaviour by consumer ideology, but this austere black-and-white version distils the concept to its most potent visual form, achieving a timeless quality that transcends moment-specific commodity critique. It is among the most intellectually rigorous of the Banksy editions.
