Character autos for Project Life

[Rincelex]

I am printing off 3x4 and 6x4 cards to collect the character autographs to go in my project life album.

I am looking for something fairly small (so that I can keep it in my bag) that I can attach the cards to so that they have something to lean on to sign their names. Here in the UK we have A4 clipboards but I can't find anything smaller.

Any ideas, I was wondering if you can buy A5 size clipboards over there.

We have mini clip boards like this:

I think I got mine at Walmart or Staples.
They held 4x6 cards with a little room around the edge.
They are put away so I can't measure but they were probably roughly 6 inches by 8 inches.

ETA: they were plain clipboards that I added paper and sticker to, and then sealed them.
