Mide Lodge #15 Oddity

Received another email with a question about another used flap which looks different. Mide and its successor Lodge Ktemaque is located just north of NYC, so Mide flaps are relatively common (for a lodge merged over 30 years ago) at local TOR’s.

In the last 20+ years that I have been actively collecting NY Issues, I’ve never seen one with a brown/khaki background. It may be the result of repeated bleaching/washings which effected the twill but not the threads. Anyone else ever seen one like this?
