Nice lot with stamp varieties and a good selection of postmarks. Stamps appear to be sound. Condition of the covers varies. Some nice corner cards. Check for fancy cancels. Postmarks include Des Moines Ioa, Media Del Co. Penna, Alexandria VA, Georgetown DC, Memphis Tenn, Maplewood NH (DPO), US Hotel art is on back of one of the covers. One cover added after photos taken is small Philadelphia cover in very nice condition.
