Card GJ.25, 1998 Film Festival of Mar del Plata, with rare VARIETY: Double impression, one on back, the latter only in cyan and magenta, very scarce, excellent quality!
VK.11 stationery envelope with the imprint in DIFFERENT COLOR (lilac instead of rose) + nice additional postage, sent from Buenos Aires to Germany in FE/1900. Possibly a used color proof? Excellent quality, rare!
