McGrew¹ identifies this v-e-r-y old face as Tuscan Outline and traces it to Ornamented No. 1071 of the 1830s by Laurent & de Berny (Paris, 1828–1840). Besides Romantiques No. 1, he lists several alternate tradenames: Carnet de Bal, Uncle Sam, Ornate No. 3 and Ornate No. 851 (Bruce).
Gray² attributes it to Figgins (London) c1846. Lieberman³ calls it Ornamented Outline available from Stevens Shanks (London); Jaspert4 concurs and adds that it was shown by J&V Figgins c1870. Thanks to the highly influential Dover books by Dan X.Solo,5 it may be best known today as Spangle.
