Here's a nice one for you CREB-heads out there. Looks to be [230] embossing, although the "T" in "45 CLIFF ST" is not underlined. From a few feet away, at first glance this one appears to be a typical yellow-green CREB beehive. However, it is really light green with extensive amber swirling. Condition is VNM, with only a flat flake on the wire rigde at rear and a tiny ISC. The piece did not photograph in my light box as well as I'd hoped, it is greener than the phots show. $275, postpaid in the US.
