Set of 36 unused vintage Halsam Interlocking "safety" children's alphabet blocks in original box packaging. Each block is 2-sided with an embossed letter on one side and a picture of a corresponding animal or object on the other (i.e. E, Elephant, B, Boats). Blocks measures approximately 1.25" x 1.25" x 1.25" and appear to have never been used - only showing minor surface wear from age (please note particular aging on P, T and R).. A truly great gift for any collector. Please note that W and X are not present in this particular set.
