The Karpens were Polish 19th century immigrants who started out making highly ornate Renaissance/Rococo Revival furniture, particularly chairs and parlor sets, then simplified their designs as fashion dictated and the 20th century progressed.
I can't recall seeing any wicker furniture of theirs, but obviously you've got a wicker chair with their tag on it so.......cool! I'd say 75 years sounds about right, just looking at the styling. The company continued for a long time, but without looking it up I think they went out of business sometime in the mid 20th century, so you've got a later piece.
