1973 was arguably Nolan Ryan's best season in the major leagues:  21 wins, 2.87 era, 383 strikeouts (new record), and throws (2) no-hitters (ties ML record).   

Also, if you collect vintage baseball cards - Canadian O Pee Chee is what collectors seek out as good investments; particularly because of the scarcity of the cards versus ordinary USA Topps.  Here's a BVG graded, VG4.5, 1973 OPC Nolan Ryan card.  The card has very nice color and presents extremely well both front and back. The corners show only touches of wear.  Centering not so great...but expected for these early Canadian O Pee Chee cards. 

Nolan Ryan is the all-time record holder for strikeouts with 5,714; holds records for no-hitters (with 7); holds the record for most strikeouts in a season (with 383), most strikeouts in consecutive seasons (5), and holds records for 1-hit games played.   Nolan Ryan is the modern day Cy Young for collectibles - all tremendously undervalued and having a huge (and growing) collector base.  You cannot go wrong with a unique Nolan Ryan collectible like this one!
