This fantastic stamp unfortunately has arrived too late to be able to appear in the documentation. Postal times from Russia are very long, almost a month. I will post it here but I will include it in a future mailart call about artiststamps, it is a too beautiful work to leave it without documentation...:-)
Hi Konstatin, thank you very much for this excellent work!!
