From Somewhere in Greece

I know it's from somewhere near Athens but I can't make out the postmark to know exactly. The stamp on the left is a Dusky Grouper from 2012 and on the right is an anti-bullying stamp from 2020. I believe this one specifically deals with social isolation.

Ernest Shackleton Postmark

From Germany. The postmark commemorates Antarctic explorer Ernest Shackleton. Shackleton died of a heart attack on 5 January 1922 in South Georgia at the start of the Shackleton–Rowett Expedition. The stamp on this cover was issued in 2001 and shows an image of the RV Polarstern: Germany's polar research vessel.

 

Polar Lights FDC, Germany

FDC postmark on a Polar Lights stamp from Germany. Specifically the Northern Lights over Lofoten, Norway. It is the latest stamp in a series that feature celestial events. The 5c definitives on the left are waterlilies but if you look closely you'll notice the flowers are actually made of letters and pencils. Smart. All are 2022 stamps with new matrix codes.

TAAF, Martin-De-Vives

I'm pretty sure I sent this to the Crozet Islands but it came back from St Paul. The stamp at the top shows the Meurthe at Crozet Island so I'm pretty sure I would have sent this there. No matter. Came back intact. Signed by the station postmaster Christophe Bouchet. Also stamped by Romane Nespoulet who mentions her stamp in her blog.

Vieux-Port De Montréal, Canada

A postmark from Montreal showing the Montreal Clock Tower and Jacques Cartier Bridge as they would be seen from the Quai de l'Horloge in the Old Port of Montreal. The old port was an active industrial port in Montreal from as early as 1611 up until 1976. Now it is used for recreational purposes and is a major tourist attraction in the city of Montreal.

  

 

Stone Chickens from Austria FDC

The stamp on the right has a pair of Steinhendl (Stone Chickens) on it, cancelled with a first-day postmark. Steinhendl is an old breed of chicken that used to be found on farms in the Eastern Alps but it is nearly extinct today. The Stone chicken is a good flyer and I guess it makes more sense to raise chickens that can't easily get away.

As much as I liked the chicken stamp I found the stamp on the left equally interesting. The watercolour artwork is a Black deadly nightshade by Brigitte Heiden. It's a loyalty stamp, not available for general sale and only available to Austrian Post stamp subscribers. It took a bit of Googling to figure that out. 

Brazilian Anurans

Anurans: frogs and toads. These three stamps are from a set of five issued in Brazil in 2021. From top to bottom: a Striped tree frog, a Manaus slender-legged tree frog, and a Monkey tree frog.

Concordia Station via Dumont D'Urville, TAAF

I always receive nice covers back from Concordia Station. This one is signed by expedition leader Rocco Ascione of ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development). The base is operated jointly by France and Italy.

USA Year of the Tiger FDC

Not only does this cover feature a USPS digital color postmark but the two stamps on the right are not die-cut. USPS have been making press sheets of self-adhesive commemorate stamps available without die-cuts for collectors but apparently they sell out quickly.

Beneficial Insects of Brazil

Three stamps from a set of six issued by Correios in December of 2021. Each stamp represents a group of beneficial insects using watercolour and coloured pencil artwork. From top to bottom: bees, dragonflies and praying mantis.
