One common issue I face when hacking Mystic pages is that I will hack the page to mount one set of se-tenants on the page, but I don’t have all the other stamps for that page.
Such is the case with Page 519. I finally bought the US Express Mail Stamp from the bottom of the page, stuck it in a mount, and it was took big for the stamp block.
So, I redid the page to correct this error.
The new version of Page 519 can be found on my Google Drive at
