Where does the signwriter go wrong? As @stevereads rightly points out on Twitter:
"Without an apostrophe, which seems to have been deliberately removed, this business name makes no sense."Quick rule:
- Always use an apostrophe when you are making a contraction using the word "is." In a contraction, the apostrophe takes the place of a missing letter; in this example, it is replacing the letter "i " in "is."
(Picture + is = Picture's)
Correction: A Picture's Worth a Thousand Words
