In April 2025, Emaillerie Belge released an exclusive, limited comic book edition in honor of Franquin and his iconic creation Guust Flater. An original drawing from 1969 was chosen for this special edition, which was craftily converted to enamel. The edition consisted of only 65 numbered copies, each measuring 400 × 330 × 20 mm. On the back, the certificate of authenticity was co-baked into the enamel, making it an inseparable part of the artwork. The series was completely sold out in no time.
