rif. 78977 — Munich Metallpapier- Bronzefarben- Blattmetallwerke Aktiengesellschaft München 1938. Three oblong booklets 8.0 x 14.6 cm; 9.1 x 16.4 cm and 9.9 x 14.0 cm. Each with a title leaf and in total 39 aluminium foil leaves each either in silver or gold one with a different embossing with brand names and logos 10 the others plain or geometrical patterns 29 and with tissue guards/interleaves with a catalogue numbers. All three stapled with gilt embossed covers two with similar leaf-patterns the other with a peculiar "fossil" pattern. = A very nice collection of aluminium or "tin" foil. "The continuous casting method is much less energy-intensive and has become the preferred process. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge and to avoid this as well as reducing tearing increasing production rates and controlling thickness for the final pass when producing thicknesses below 0.025 mm 1 mil two sheets are rolled at the same time doubling the thickness of the gauge at entry to the rollers. After the rollers the two sheets are separated which produces foil with one shiny side and one matte side" Wikipedia. In one several plain leaves are creased deliberately so but otherwise all three are considering their age in excellent condition. unknown
