Currently we are thoroughly watching over the situation in Ukraine and trying to support the brave and unstoppable
spirit of Ukrainian nation in fight against Russian invasion by donating to the official resources provided by the
Government. NING is standing with Ukraine in this fight for freedom and independence and if you want to show your
support you can donate here.
Not my area of expertise - unable to ascertain if these are perhaps authentic Castro signatures, secretarial, or preprints? Perhaps someone has seen something like this before?
Appreciate any insight or opinions you may be able to provide. Thanks!
