As can be seen in the images to the right and below, there are seven different pairs of the special glasses designed after some of the major characters from the upcoming film (via Comicbook.com). Iron Man, Captain America, Thor, Hulk, and Black Widow all are represented, as is new Avenger Vision and the titular villain, Ultron. Noticeably absent are pairs designed for original team member Hawkeye or the other newcomers, Scarlett Witch and Quicksilver.
Below is a British ad for the glasses noting a £3.95 each or three for £10.00 price point. That would translate to about $5.89 for one or $14.90 for three, though there's no guarantee these would be the actual retail prices.
"Avengers: Age of Ultron" hits US theaters on May 1st.
