Well, this thread made me go dig through my 1980 Topps cards...and you're right, this really is a good set. The pictures and design are great.
Speaking of great pictures, as I was going through the cards, I stopped to appreciate the Tim Foli card. Who is Tim Foli you ask? I have no idea. But take a look at this...between Tim's expression, the action, Youngblood's awkward arm angle in the slide (???), Tim's autograph penmanship, and those old time Pirate uniforms, this makes for a GREAT card:
