Acorn Tattoos are popular in terms of the nut category it's associated with but uncommon in the mainstream of art. This tiny seed of the oak tree largely represents birth, life and even death. In ancient Scandinavia it was sacred to Thor who believed it symbolized fertility and immortality.
Aegishjalmur or Aegishjalmar Tattoos are somewhat of a mystery because of the huge variety of different designs and their meaning is only truly known by the designer. There are literally hundreds of these tattoo images to choose from but the vast majority typically begin with a cross at the center that increases in area and intricacy. They are considered by many to represent protection or an aura to shield against negative vibes and bring positive remedies.
Alcohol Tattoos and most other types of artwork portraying various types of drink are typically integrated in the famous Man's Ruin tattoo due to its addictive properties when abused and the change in behaviour it can cause when one becomes intoxicated. Many tattoo images are depicted with other illustrations such as the skull and crossbones which give heed to its users, abusers and worshippers.
Alien Head Tattoos were almost unseen until the now famous event that apparently happened during the 1950s in the USA. Many believe that a UFO crashed in Area 51 with an alien life form onboard, with both being captured by the US military. Numerous images were released but never proven and with this artists began creating their own alien tattoos that usually showed a creature with a big head and large black eyes. Flash designs are still on show in most tattoo parlours but it appears to have had its day.
