Several months after first soliciting suggestions, the Niners Nation bricks are live and in color at Levi's Stadium! I received copies of the bricks in the mail, but I wanted to wait to post pictures after we could get pictures at the stadium. EastBayNinerFan was kind enough to get some pictures of all three picks. I have posted them below.
For each brick, the first picture is a close-up shot. For the first and third bricks, the second picture is further away so you can see where it is in relation to the stadium and other bricks. For the second brick, there are three total pictures, just to help you find it. Additionally, at the bottom I have posted a map EBNF produced that includes green dots with the location of each brick.
If you get to the stadium, make sure and get a picture with one or more of the bricks. According to EBNF, since the car park at the stadium (entrance on Tasman Drive) shares with Great America, security is letting people park in the Niners section free so people can wander around the outside of the stadium (free) and they can also go into the shop and they can get to the Museum ($15 each). This obviously will not happen on game day, but it is something to keep in mind if you swing by the stadium on an off day.
