This is a bit of repost, but seemed a good idea to put this with its brethren.
All movie paper for Alice in Wonderland's initial release is by and large fairly rare, but here is something I never thought I'd see - I wondered if it even existed at all since it is not listed in the campaign book!
This is a 40x60, slightly smaller than a 3-sheet (41x81). The major difference is this is printed on a single sheet, and it is a heavier paper stock, more like lobby card or half-sheet stock. It does have the NSS number 51-408 printed in both the upper and lower margins. Odd that this particular size is only known by its dimensions, their is no 'name' for this poster size
