Houston Astrodome Astros Turf Invention NFL Baseball 4x USA TX Postcard s

ts345  This is a rare and stunning undated but appears late 1980s to early 1990s collection of postcards all of the Houston Astrodome and this spectacular sports centre (one of the greatest in the world) the postcards showing mixed views of night, day, and one of the card I believe shows an NFL game and reads on reverse how grass wouldnt go there so they have now invented Astroturf which the card shows the players having the game on (manufactured grass especially made for the stadium) - All are unused and mint and a specialist collection of postcards from the same original Houston sports collector.
