France 1875 Ceres 1307 Dijon Bureau de Passe Cover Mulhausen Horseshoe

Folded letter, with contents, franked with 15c bistre and 25c blue Ceres, tied by superbly-struck 1307 "Bureau de Passe" c.d.s. (16 Oct), adjacent Dijon c.d.s. of same-day, oval "BM" (Boite Mobile) and red boxed PD, to Mulhausen, with fine strike of Mulhausen-Elsass horsehoe (Hufeisenstempel) (17 Oct), a beautiful and scarce cover, the Bureau de Passe c.d.s. being particularly desirable tying the adhesives, further complemented by the Boite Mobile usage and horsehoe receiver. (Yvert 55, 60)
