Ten of Diamonds

Look at the faces of these engineers
Focus on those in the center board here.  
One looks out on many ships at a dock; 
One guides a horse in a leap--what a jock(ey).  
One and his wife with binoculars roam;
One stands in front of the Charles and the Dome.
Faces in caricature here look out proud, 
As one lies on his back under the clouds.  
White tie and black shirt--last one's cool, with no doubt
From their names find a topic they might talk about.
