This picture was taken on August 6 1920 at N

The same location some 85 years later.
To find this cache you will have to identify
the famous Lady shown in the medallion and also standing by
the car. Once you know who she is do the following
calculations.
X1 =
day of her
birth
Y1 = day of her death
X2 =
month of her
birth
Y2 = month of her death
X3 =
year of her
birth
Y3 = year of her death
To get the UTM Zone 18T Easting coordinate:
(X1 x X2 x X3) ÷ 0.539153872
To get the UTM Zone 18T Northing
coordinate: (Y1 x Y2 x Y3) x 10.02832259
As usual any spoiler will be deleted
immediately. Good luck.
