A technical patent drawing rendered in classic blueprint style shows interlocking brick components across six detailed figures, each labeled and rendered in white linework against a deep blue ground. The composition combines the precision of engineering draftsmanship with the playful geometry of construction toys, creating a nostalgic yet architectural study of a beloved object's mechanical artwork. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
