Era is one of the most important aspects of a good design investment. When looking for something of a particular era you should take the time to learn as much as possible about that era to maximize what was hot then. This can help you figure out who the big designers were at the time and the colors and styles that were most popular. An example of this is seen in Danish design with the ever popular designs from the 1950s. This era has continuously shown up throughout the last fifty years and proves time and time again to hold value and be worth the price many pay for the investment. The style is also a classic and the colors are inviting and inspiring toward the rest of the room design. Another key factor when considering era in a design investment is to look for pieces from eras that has proven to stand the test of time. These include the Bauhaus period and Le Courbusier. Both of these product lines are considered non-responsive to trends and thus are popular consistently throughout the years. Another thing to consider when looking at pieces by time is the condition of the piece. For the piece to be the most valuable and desirable, it should be in incredible, preferably original, condition.
