SW DV-307 SW FO-493 Houston - most populous city in Texas

Houston is the most populous city in Texas and the fourth most populous city in the United States. The city is estimated to have a population of 2.2 million people within a land area of 599.6 square miles (1,553 km²). Its metropolitan area has over 6 million people.

Houston was founded in 1836 and incorporated as a city in 1837. The city was named after General Sam Houston, who was president of the Republic of Texas and had commanded and won at the Battle of San Jacinto 25 miles (40 km) east of where the city was established.

Houston is the largest city in the United States without formal zoning regulations. Voters rejected efforts to have separate residential and commercial land-use districts in 1948, 1962, and 1993. Consequently, rather than a single central business district as the centre of the city's employment, multiple districts have grown throughout the city in addition to downtown which include Uptown, Texas Medical Center, Midtown, Greenway Plaza, Memorial City, Energy Corridor, Westchase, and Greenspoint.

I have received two postcards of Houston.  The first postcard came from Sabbysteg (30 September 2014) Swap-bot and the second is from Diane (fabriqueen) (8 June 2015) Swap-bot.
