The Iraqi postal service has issued new postage stamps honoring two of the country's beloved architects: Zaha Hadid, who died in March, and Mohamed Makiya, who died last year at the age of 101.

Hadid and Makiya both changed the perception of architecture in the Arab world and introduced some of the aesthetics of Arabic-inspired architecture in projects around the world.

Hadid's London-based firm designed buildings around the world, including Lebanon, Spain, Germany, and the United States, as well as the iconic, if controversial, al-Wakra World Cup Stadium in Qatar. She was the first woman to receive the Pritzker Architecture Prize in 2004.

Baghdad-born Makiya is best known for the extension to the Khulafa Mosque in Baghdad, which integrated old and new sections of the mosque featuring a minaret dating to the ninth century.

The stamps go for 750 Iraqi Dinars, or about $0.64. If you happen to be in Iraq and have a pen pal there, these stamps may see some use - otherwise, they're likely to be snapped up by architecture aficionados and stamp collectors worldwide.
