Description

Vintage Antique Greene-Brown Manufacturing Electric Power Supply Ad Brochure c. 1928 Radio Show - Chicago
This measures ~6" x 3.25" (folded up) -- ~12" x 18.5" (opened)
Condition is 'used'. This is in very nice condition considering its age.  This came from the estate of a collector of vintage/antique radios and radio related items.  The bag it came in is labeled with '1928 Radio Show - Chicago', and I'm assuming that is the correct origin. See photos for condition and detail.
Please look carefully at all photos. The photos are an important part of the description. If you have questions, please ask.
