These are two official maximum cards (MCs) produced by the World Wildlife Fund, on behalf on Paraguay Post. Very interesting animal. I shouldn't have to provide direct links to wikipedia, etc. each time. You should read further on your own, if you are really interested.
Am I right? :)
Do you notice the young one, riding on mother's back - both on the postcard and on the affixed stamp? Hold on for dear life, baby...or else.
Look at these maximaphily pieces. Are they perfect? No.
Why?
Because of the placement of the stamp, and the postmark.
They could have been better placed on the upper left corner, without obscuring at all the animal's image. Do you agree?
What else?
The subject of the pictorial postmark. Yes, it's the WWF logo, the lovely giant panda. Most postmarks applied from WWF HQ in Switzerland have it. Only some local issues of such MCs have non-panda postmarks, such as the tigers from Russia - with tiger postmarks. See the tiger cub in the grass MC here:
The Paraguay MCs postmark is good, clean and clear. It could have been even better - perfect - if it featured a giant anteater, instead, for maximum concordance.
Overall, I like it, and I'd love to get or create more maximum cards/ maxicards/ maxi cards/ dorincards with the exotic (for me) wild mammals of Paraguay. :)
