The little slashes are dots to go over the A like this EKENÄS
Excellent close ups of the signatures Tony, which also show great detail of the colors and internal decor.
Ekenas was founded in 1917 by two former workers from Orrefors. The factory has had several noteable glassblowers amongst its staff including Edvin Ollers (1940-47) and Micahel Bang during the 1960s (more famous for his work at the Danish firm Holmegaard). The Ekenas factory closed in 1976.
