Foxhole radios

The razor blade division of Marlin Firearms ran a campaign in 1944 - 45 centered around a “foxhole” radio receiver that a soldier had made at Anzio using one of their blades. It got a lot of publicity and from what I understand the campaign was a success.

I’m looking for anything related to the campaign, including a better copy of the picture I’m attaching or any of the display material used. Unfortunately the marlin razor division is long gone and none of their records were archived. Let me know please if you have anything related to this campaign.
Thanks!
Sincerely,
Brian Carusella
