Photos and compositions during the 1920’s incorparated themes that became symbolic of that time period. A changing life style along with trends were inspiration to various posters and related illustrations. Colors of high contrast and saturation are common and gradually changed with time. figures and charaters appear vibrant due to their expression of movement which relates to popular music of the time, jazz. A growing middle class provided a platform where new products and services were sold, this influenced themes of change and a new age. Besides color, most charaters and objects seem to be drawn rather than the use of photos. Today hand drawn images seem to be intensionally done and not out of necessity or the lack of technology.
I believe that most posters of this era expresses an organic feel which seems to have gradually disappeared. Some drawing in these images represent the personality of the artist. Type is also an area were a lot of personailty can be drawn from, today it seems most compositions are restricted or aim for a professional san serif look. While i prefer san serif type, i think experimentation can be more attractive. Personality within a composition can be achieved with unique hand done work, but i also believe good use of photos can capture the same feeling.
