I have a copy of an 1897 Sear and Roebuck Catalogue on page 225 there are hadkerchiefs ofne is listed as," Men's Handkerchiefs. Genuine Martha Washington Turkey Red Handkerchiefs these are the Old Reliable, Fast Colored Standard Quality Goods." It then goes on to state they come in
18x17 inches;per doz..... $0.43
21x20 inches; per doz..... .55
24x23 inches; per doz..... .65
28x26 inches; per doz..... .90
So I guess it depends on how rich a cowboy was when he ordered as to what size. As to linen and silk most of those just say,"Full" size or some such.
On page 226 there is a close out sale each an odd lott of mens mufflers at $0.23 no size given and then there is ,"Pure Silk Mufflers" for ladies or gentlemen, handsome broacaded patterns, of pure silk, in a variety of designs; size 28x28.
Each............................................................... $0.80
hope this helps.Celeste
