A return to the "Miss St Petersburg 1974" box of slides.  Maybe if you're good, you get one of the Swimsuit Round slides tomorrow. Maybe.  (Edit. Damn. A duplicate.)

Anyway.... the fashions .... wow.  And it appears that the chap in the centre is Dave Miller. OK.

Bonus - Institute of Illegal Images in San Francisco, California, and their collection of Blotter Acid.
