The following posters were designed as a cheap way of getting 24"x11" posters from a regular printer by breaking up the image into three pages. Below each picture there are 2 links to pdf files. B points to a pdf file with all the three pages, while S1 points to the single page version.
How to use: Print the B pdf file with Adobe Reader and select the "Fit to Page" sizing option. Page 2 has two grey cut lines, cut a little on the inside of those lines. There's about a half inch overlap, so you don't have to be too careful. Align Page 2 over Page 1 and Page 3. Then with small pieces of tape, tape the edge of the seam to a table top. Then tape over the full seams on the front, and then the back. The poster can be hand held or it can be taped to a piece of foam core (Dollar stores have them).
