Ha ha! My thoughts exactly!!!!!!

I guess that earlier post by Darren is why I had mind

This has probably been noticed before by others, but I found it and have it here. The blue line recurs a LOT as about half of these cards have it.

That mark is similar to one that's found on a few Johnson (glove at chest) T206's.

Post 692 in this thread shows a few additional progressions to the blue line seen on this card.

Here's a strange Joe Page 1950 black reverse overprint I found, the subject of another thread.

How do you find the post # mentioned?

As an example, here is a link to 692

Otherwise using the manual process of scrolling through the thread looking for it......

....or describe what you are looking for in a new post and hope someone here goes and finds it for you :)

Actually, the post can be found by going to the top right corner of the thread and click the down arrow next to the page numbers. Then divide the post by 10, and go to that page (or the one next to it). Presuming you have the standard 10 posts per page. If you've changed your preferences to change the number of posts per page, divide that number.

And since I'm here:

Looks like a bunch of Laughlin #32 were printed without the black ink pass, so that the 11-0 is transparent. Not sure if these cards were printed as one card per sheet, or if this would be widespread across the rest of the series.
