This really looks like Impression Obsession to me but, i bought this on ebay and its possible the original owner self-mounted it. (it had a paper index with packing tape applied to the woodblock when i bought it)
Cynthia Hart (designed this) but no idea on the mfg...
shaped shoe, no markings on the wood mount
Quail Purchased at Stampstruck a few years ago, no marking on the wood block.
was an unmounted piece of rubber gift from an ebay seller... (self mounted)
