Arthur Umanoff's 1964 Grenada Collection for Boyuer Scott is quite possibly the most frequently mis-attributed of all of the Boyuer Scott and Shaver Howard collections. It's vague similarities to Salterini's 1951 Tempestini designed "Scherzo" or "Ribbon" collection coupled with a sum-total lack of available documentation on the Boyuer Scott production has provided ample fodder for error and misattribution even amongst some of the most reputable and scholarly dealers.
