In 1880, Portugal recognized Romania's independence. Celebrating the 130th anniversary of this event, Romfilatelia issues the joint stamp issue entitled "Ceramics – Tiles".
The stamps feature:
- A Saxon origin tile from Bistrita-Nasaud County, dating back from the half of the 19th century, which belongs to the patrimony of the Romanian Peasant Museum in Bucharest.
- An Azulejo, dating back in the 18th century, Lisbon, from the collection of the National Tile Museum in Lisbon.
Azulejo is a word deriving from the Arabic word al-zulayi (meaning "polished stone"). The Azulejos are painted tin-glazed tiles used to cover large surfaces, either inside buildings or on their facades.
