From numerous episodes.

I purchased this item online.

This was made as part of a project on an internet prop forum. it is laser cut aluminum, and is VERY nice. This was my first Smallville prop. The lettering on the key is accurate to the keys shown in the second season. From what I understand, the text on the key changed during the course of the show to suit the needs of the particular script. A friend of mine is making a different version of they key which I hope to acquire soon. Downloads: Kryptonian font for the PC.
