The similarity between the two Historical posters is that - Both posters use images to attract attention and help convey a message.
What are Posters?
Poster is a temporary promotion and set up of an idea, product, or event put up in a public space for mass consumption.
Predominantly, posters include both textual and graphic elements, although a poster may be either wholly graphical or wholly text. Posters are designed to be both eye-catching and informative.
Posters may be used for many purposes. They are a frequent tool of advertisers, propagandists, protestors, and other groups who are trying to communicate a message among people.
Posters are also used for reproductions of artwork, particularly famous works, and are generally low-cost compared to the original artwork. The modern poster, as we know it, however, dates back to the 1840s and 1850s when the printing industry perfected color lithography and made mass production possible.
What are Images?
An image can be described as an artifact, such as a photograph or other two-dimensional picture, that resembles a subject usually a physical object and thus provides a depiction of it.
An image is a distributed amplitude of colors. A pictorial script is a writing system that employs images as symbols for various semantic entities, rather than the abstract signs used by alphabets.
Images may be two or three-dimensional, such as a photograph or screen display, or three-dimensional, such as a statue or hologram.
Images can be captured through optical devices – such as cameras, mirrors, lenses, telescopes, microscopes, etc. and natural objects and phenomena, such as the human eye or water.
