Two UNIMA “Budapest 1966” graphic cards, signed Jan Malík, with mailing envelope

One UNIMA printed-matter envelope retained with two near-identical cream paper graphic cards. Each card has a bold abstract black/brown and blue/purple design incorporating the words/numerals “1966” and “BUDAPEST”, and is signed in blue ink with a name that appears to read “Jan Malík”. The envelope is addressed to “THE LAUREY PUPPET COMPANY (Miss Joy LAUREY) / The Puppet Studio / TIPTREE, Essex / ENGLAND” and carries the UNIMA logo, the French title “UNION INTERNATIONALE DES MARIONNETTES”, Prague return details and a Czechoslovak postal meter.
