[R-390] Finding attachments

[Perry Sandeen]

Yo Bubba Dudes!,
There have been attachments provided for different designs of pictures but when I copy and past to both Google or Edge I end up with a can't be found message.  

For example:
URL:<http://mailman.qth.net/pipermail/r-390/attachments/20190613/8918b790/attachment.pdf>
Could some please post the step(s) or method(s) of how to get these types of attachments?
This seems a common method of posting but I'm completely lost.
Regards,
Perrier
