California Tower, at Balboa Park in San Diego.

The area here is so overgrown now, in the Southern California year-round growing season, that it's impossible to appreciate the beauty of these remains from the Panama California Exposition of 1915.

This water colors captures the spirit of the place, as I have experienced it in direct contact.

Balboa Bridges, Charles Arthur Fries, 1916

The cover of the guide book is a more photographic image, water-color as well but with a different sensibility.

 I much prefer the more impressionistic.
