Mein erstes Buchstaben-Spiel (1986)

This game consists of the 26 letters of the alphabet. While "y" is only one card, the other 25 letters are "puzzles" of two cards each. One side depicts an item, the other one the spelling. There are three games described in the rule. One is "Old Maid" ("Schwarzer Peter", or, "Das schwarze Ypsilon" in this case), one is a trump game in which the letter which appears first in the alphabet is the winner, in the last one the players have to form words with their letter cards.
