Got a Free Vintage Card from SwagBucks!

Hey guys, I recently got in this 1966 Topps card of the 1965 NL MVP and Rookie of the Year, Frank Linzy. The cool part about this one though, is that I didn't pay a single cent for it, even for shipping:



I used a site called SwagBucks to get it. All I had to do was search on their engine, and after about 4 days of using it just like I normally would Google, I got enough "Swag Bucks" to receive this free 1966 Topps card. You guys should check it out. I am on my way to another free vintage card right now!

And this card is for trade. I am no expert on vintage, but it seems the card is centered quite well. If anyone could let me know an approximate value, that would be great.
