Unusual Railroad Cancel. Any Thoughts?

I saw this on ebay and it looked odd, so I figured I'd take a flyer on it. Scott R86c, the $3 Manifest, with a blue circular handstmp cancel, and then what upon receipt I initially thought was document offset... but now I don't think so.

There's a large black ornately typeset boxed cancel (or what I believe is a cancel) that mirrors the company name used in the circular handstamp: Lehigh Valley Rail Road Co.

The lightness of the black area has all the characteristics of document offset rather than a cancel, but if it were offset, it would be a mirror image.

Has anyone seen this or a similar item before? It's not listed in Tolman.

pretty difficult to makeup.
My guess would be the Lehigh Valley R.R out of Pennsylvania.

Oops, but on reviewing your post again, you already knew that. Sorry.

Maybe an anti theft mark, sort of like a perfin??? Nice stamp though, Good eye.
