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 on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
