Hi Moey you asked me what mini ecrits are.
Paolo explained this about it :
They are mini-recits, and they were inside spirou magazines back in the 50's or 60's so they are very old and they were built by folding many times a big A3 size paper (so I believe their size is an A6).
A4 is the common size paper here in Europe (similar to the letter size that is used in the US), and if you fold an A4 sheet you get an A5 and if you fold it again you get an A6 (about 10cmx15cm).
Those mini-recits are hard to find in mint conditions and currently on ebay there are many auctions, but all are pricy.
But these are the newest version of it. And already folded in a mini book.
