I've just launched a new campaign on Indiegogo.com for printed A5-sized pads of OSR Character Sheets. Full details can be found here:
OSR Character Sheet Campaign on Indiegogo.com
The sheets are designed for use with B/X rulesets of the world's most popular fantasy roleplaying game, and retroclones versions such as Labyrinth Lord.
This is a small project to test the water, but if it succeeds, I have several other, larger projects in mind for the future. A PDF of the character sheet is already on the site, so please help yourselves to a download (in the Gallery section of the project page) if you like the look of it.
If you want more detailed character sheets, the set I designed in 2010 for use with Labyrinth Lord's Advanced Edition Companion rules are also still available as free downloads on RPGNow.com.
