For thousands of years, several characteristics have been consistent across human Societies around the world. Animal husbandry, agriculture, and artistic expression are some of the similarities all societies share. Another similarity is the mustache. So now I mustache a question why have mustaches had such a notable presence in human history! Humans have been shaving for as long as there has been facial hair to shave. However, it is in the past several centuries that mustaches have undergone a more creative transformation. Now, there are many different types of mustaches. The Handlebar, Pencil and Walrus are only a few of the many types known today. With just a sharpened razor and some mustache wax, the creativity of people and their mustaches can be endless.

Though the popularity of the mustache in different cultures varies over time, has certainly influenced other creations. In the 1800s and early 1900s, mustaches were so popular that a new style of drinking cup, the mustache cup was created. The mustache cup had a built-in covering over the top so mustaches would not be touched by the beverage. A more recent example of the mark of mustaches can be seen by the first World Mustache Tournament in 2013. The mustache truly is part of the human experience due to its place in the human experience, the mustache is a symbol with varied sentience power prestige beauty.

A day with Humpbacks

I sat on the deadlands of Neah Bay, Washington, and watched a mother humpback and her calf slip through the icy Pacific waters. I recognized this humpback by her distinctive tall patterns, as unique to her as my fingerprints are to me. Once, heavy hunting using harpoons decimated populations of humpbacks, but they have since started to recover.

As this gray female rises to the surface, she exhales, sending up a spout nearly 20 feet high. She rolls on her side and lifts her scalloped edge flipper in salute, then slaps it on the water. I adjust my lens and take a shot. This is the only type of whale hunting I find acceptable – hunting with a camera!
