Model Railroad Hobbyist has a photo of Clever Models display layout in their, Feb 2014 issue , Amherst Show Report article. They note that the models are made from cardstock. Their comment "Impressive!" is well deserved.
The "Get current issue" link is still to the January issue (as of a couple minutes ago - 6:50 Pacific Time), but if you go to the "Publisher's Musing - intimidated or inspired" post you can get the February issue.
Don, got to see it today on page 104. thanks again for the heads up. we also got a mention in the rollingstock boxcar article. nice just to be included in the list with the BIG guns.
