Borders and Color
Color and shading play an important role in the images presented by each series of postcards. Again, these differences might speak to some ideological changes present between the two time periods. Overall, the color scheme of the postcards from 1904 are muted and somewhat subdued. While the attire of individuals might occasionally stand out, the images sit well together and artificial seems to blend together well with natural. In the 1933 Chicago cards, though, color is used in a more vibrant way, with buildings rendered in colors that stand out from the surrounding natural features, perhaps again emphasizing the different viewpoints regarding nature and culture. Even the shading differs in the Chicago cards, where colors are often used as flat shades with less texturing or blending, perhaps speaking to a more technical mindset.
Even differences in the manner of borders present on some of the St. Louis cards speak to a different mentality. Artistic flourishes and soft borders are characteristic of the 1904 postcards, with scenes fading out gently into the background cardstock. Chicago, alternatively, makes use of white, clean borders that clearly demarcate where an image ends. Because of this, the St. Louis images seem more expansive--designed to capture the feel of a moment rather than every last technical detail.
