Antediluvian Alterations

I recently uploaded a bunch (sorry about the use of technical jargon, there) of transparencies from 1991 to my photobucket trans account. This was the year of Fun With Filters, when I really got stuck into the Cokin system, and I found that a fair few fore-echo the Altered Images series of mucking about with deconstruction and abstraction.
Here, without title or commentary, are a few of them.
