I've just finished making a pocket grammar guide for French, Spanish and Italian: Here it is.
As with my other pocket grammar guides, each page will be 1/8 of an A4 page, thus allowing you to have the basic grammar of all three of these languages on a single sheet, which is then folded into a little booklet.
I would be very much appreciative if someone looked through this and pointed out any mistakes or made suggestions. In order to fit a lot onto it, I've had to be quite concise, after all.
Proycon's comparison table was very useful for this.
