The German book ‘Alles Uber Zimmerpflanzen – Sukkulenten” (All about houseplants – Succulents)  published in 1985 features a Marei Plant pot. My photos unfortunately dont really do the original image justice. The plant pot in question includes the signatuture Marei glaze decor where it appears to have been splashed onto the item and  applied to the simple utilitarian shape used by Marei.
  
Below are clearer photos of a Marei plant with a similar type of decor.
