Look at this cool promotional Sonic. He's a big stand-up sign to attract customers wherever it's placed. Here, it stands outside of a video game retailer in a mall in Finland. It's a classic item, and has stood there since some point in the 1990s, until its sighting here in 2011. (at left) However, in 2012...it was aquired by a fan! At right, you can see it in a home, to get the idea of the size. It still looks just as good as in the first photo, which means it has to be quality, not some lame cardboard that would fade or bend. It is remarkable, for being such a long lived store display. 

The base is metal (likely steel) while the Sonic part is some type of wood with colored coating. These materials likely contributed to make it sturdy & long lasting. It's 110 cm high. The game shop it was in front of closed. When it did, they sold off the fixtures (including the sign) It went to a fan, who later sold it at auction. Sign now owned & info by Sonicfan3841
