Ok, so I think the question posed in the post title is really impossible to answer with any definitely. Essentially, card collecting is a very subjective hobby, but every now and then a card comes along that combines great design, color, photography and a HOF player. This is the case with the 1980 Topps Rickey Henderson RC.
Not only was Henderson likely the best lead off man in MLB history, but the '80 Topps card features a classic 70's/80's card design and iconic batting stance. The Oakland A's green and yellow team colors also brings the whole card together. This is a must have for any baseball card collector, and I was glad to add the Henderson RC to my collection a few months ago.
To some, the 1980 Topps Rickey Henderson RC is the best looking baseball card in the hobby, to others it's not, but there's no question that it's certainly worth noting. What do you think? Is this the best looking baseball card ever, or at least in the conversation?
