Both are in excellent to mint condition. This looks like an early Allach mark with the stylized B above a green wavy line and then on one cup and saucer there is what seems to be a sticker or stamped type mark for Grife & Escoda. They were both in operation  at the same time so I don't know, any info would be appreciated, perhaps  Grife purchased and sold them through their company to hotels and restaurants in Spain. I believe there are other examples of double marks for this purpose. The Grife marks looks to have been applied after firing as one looks wrinkled and the other raised . One cup/saucer only has Allach mark. Very confusing.These are tiny cups at about 2.5 inches tall and they are as thin as eggshells not at all like Grife pottery. There are also some very faint incised zig zag marks on one cup please see all pics.
