This Post Has My Stamp of Approval
Among my interests is a wee bit of philately (stamp collecting). I have managed to gather a few eclipse related stamps over the years and herewith proudly display them.
Senegal experienced a TSE in 1973.
This is a mini-postal sheet commemorative of the 1999 TSE in Hungary.
The US Postal Service has no plans for a stamp to commemorate the August 21, 2017 eclipse. I wish they did.
If you want to see more of these, Front Page Science has a page devoted to eclipse-related stamps.
