There's an application called fbgrab provided by the fbcat package that (as the name might suggest) grabs a shot of the current framebuffer. This might not work on newer KMS setups.
sudo apt-get install fbcat

If that fails, you could always use a VM in VirtualBox.
If you want to take a picture of another TTY, fbgrab takes a -c N argument (where N is replaced with the /dev/ttyN you're using).
To take a screenshot of the first virtual console (AKA screendump) and save it to a file called "screenshot":
sudo cat /dev/vcs1 > screenshot
Using this method, the screenshots are saved in plain text format, not an image (check this with file or mimetype command). It simply outputs a screen dump and then EOF. Note that the output does not contain newline characters, so some processing may be required:
sudo cat /dev/vcs1 | fold > screenshot
fold wrap each input line to fit in specified width (80 by default).
You cannot take the screenshot of a virtual console when graphics is enabled.
