Can anyone provide the date, approximate or otherwise, when EJ & I started their orange stenciling scheme with the “Around Chicago” route map? Thanks in advance for any help.

Larry, those cars were photographed a lot when they first appeared, for obvious reasons, and I have several photos of them taken in 1950, the earliest having a reweigh date of 4-50.  So I would be surprised if they appeared any earlier than that.
