HI,
I've posted some of Ralph Erickson's photos of the 70th Tank Battalion on Ron George's site. Right now they're on page 7, and if not, the key word is 70th for a search.

These show a 70th Sherman fitted with 'chicken wire' for foliage camo, as well as the same tank with camo applied. Also, a line up of 70th tanks in Germany. This shows the variety of tanks they used at one time. The photos were taken by Ralph and couldn't always be safeguarded from the elements.
Ron.
