The only stamp Czeslaw Slania has engraved for Estonia is a joint issue between Sweden and the three Baltic Countries, Estonia, Latvia and Lithuania.  Although Slania has only engraved the stamp in the top row to the right, I have chosen to show the full sheet, featuring the birds of the Baltic.  Similar sheets can be viewed on the pages for Latvia and Lithuania respectively.

Please see below for an explanation of the individual stamps.
