CONTRACTS CALL FOR USING TOTALS OF AT LEAST 20,000 FT OF FRAMING LUMBER AND 8,000 CUBIC FT OF CONCRETE; AND AT LEAST $9,000 FOR PROMOTION AND ADVERTISING. EACH CLEVELAND CASTLE REQUIRES 4,000 FT OF FRAMING LUMBER, 1,000 CUBIC FEET OF CONCRETE AND $1,000 PROMOTION AND ADVERTISING. EACH PITTSBURGH PALACE REQUIRES 4,000 FEET OF FRAMING LUMBER, 2,000 CUBIC FEET OF CONCRETE AND $3,000 PROMOTION AND ADVERTISING.
