These cards were issued in 1970 and 1971 and each year appears to be the same. They were sold thru the mail and the series was called All Star Pack. They were issued by F. R. Woods House Of Baseball in Cooperstown, New York. They came in an envelope and cost .75 cents at the time. Each is about 4 1/2" x 7 1/4" and is on thin linen paper stock and blank backed.
