HOW TO PUT A PROTECTIVE CAP ON A CAB

To protect a specimen cab, often a cap is needed. In my case, I had a slab with the because of the color of the background and the pattern.

The famed rose gardens of Buenos Aires are one of that capitol city's major attractions. Red roses also figure prominently in Argentinian art and festivals; they are even an economic factor as the nation's third largest export.
