Purist collectors yearn for the first ever made of their specific obsession,
the  oldest surviving example of their items of acquisition.

In November, 1885, Gottlieb Daimler installed a smaller version of an engine
in a wooden bicycle, creating the first motorcycle.  It was named the
Reitwagen ("riding car") and reached the dizzying speed of 7 miles per hour.

This outfit is believed to be the oldest complete

women's gown to have survived intact:

 The ensemble was worn by Mary of Hapsburg,

Hungary, between 1510 and 1520.

The outfit is a typical early 16th century Burgundian gown with

a high belted waist, wide neckline and smocked blouse underneath.

Constructed of green damask silk, the neckline is trimmed

in gold brocade and the blouse is finely woven linen.

Antiquity hunters of one-of-a-kind music instruments
would love to add this to their collection:

Is it a guitar?  No.  Is it a lap harp?  No.  It's an Apollo Lyre.  Made
in 1848, it's the only known example of its kind.  Inspired by the
melophone, another extinct dinosaur of the music instrument world,
it produces a sound between an accordion and a harmonica.


The first automatic tea (or coffee?) making machine:

Patented in 1905, this invention changed the world of early commuters
forever.  (Just remember to wind the clock before going to bed.)


The first Apple computer:

Dubbed Apple 1, this is the beauty that changed our world.  Hand-built by
Steve Wozniak in 1975, it was used for the first time in a California high
school math class then donated to a community public access computer center.


So, the big question - where's the first cell phone ever used?

Martin Cooper presented the world with the first cell phone in April, 1973.
About the size of a brick and weighing 2.5 pounds, it wasn't available to the
public nor even used commercially.  Cooper had spent years developing the
technology to show that a wireless phone was possible.  But, after his phone
was acquired by Motorola, it only took 3 months for it to go into production.

 
Mr. Cooper ('Coop') shown recently with his first wireless phone.
Just imagine - if today's marketing had been around in 1973, we'd
be calling our portable phones something other than a cell . . .
 now where did I put my coop?
