73's was really the first ones I collected card by card seriously as a kid. Despite its overall unattractiveness its one of my favorite sets to this day. There were a lot of those airbrushed cards and weird actions shots that year for sure. The A's had won their first world series the prev season, so I was so anxious to get some of the players...I remember seeing Joe Rudi's card and was like wth? It was Gene Tenace.
Here is a good link about that card.
