What was the original shape of Edison's electric light bulb?

It was approximately the shape of a pear with a sharp point on the center of the large end where the glassblower had left a tube thru which the air could be removed using a vacuum pump. After the air was removed this tube was heated again to cause it to seal the vacuum inside the bulb and the extra length cut off leaving the sharp point.

It did not take long before (for safety) this tube was moved to the narrow end, where it could be covered by the metal screw in base leaving the large end smooth. This is the way all modern incandescent bulbs are made, however the shape of the wide end now comes closer to spherical than pear shaped (although modern incandescent bulbs can be obtained in nearly any shape: flame, globe, retro, cylinder, etc.).
