- Who is the Mistake poster for?
- Mistake belongs to the Law section rather than to a school year, because law & society is not something one grade owns. Anyone learning contract can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Mistake poster?
- The doctrine is narrow. Most mistakes about value or quality do not void a contract. A wall chart earns its place by being glanceable from where the work is happening, so Mistake belongs on the wall where that law & society work actually happens, within glancing distance, rather than filed away.
- What other posters go with Mistake?
- Agency, Breach & Remedies and Consideration sit alongside Mistake in the Law section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AgencyBreach & RemediesConsideration
- Is the Mistake poster free to download and print?
- Yes. Mistake downloads as a free PDF with no account, no email and no watermark, like everything else in the Law section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Mistake poster print at?
- Mistake is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Mistake loses nothing.Printing guide
