Thanks for the input, TheAitch. I see my challenge will be to determine a clear-cut winner in this contest; many of you have submitted a number of excellent designs based on a theme, - thanks for that variety. Some designs may prove to be too complex, although you've all done well taking my suggestions and incorporating as many elements as I can toss out, often on a whim.
Yes, I anticipated many similarities between individual designer concepts, It's the occasional "oddball" that has really attracted my attention... the first received being #3, upon which many of you have picked up and carried forward; then the "herald" styles too numerous to mention; and now a builder's plate (#56). I love the creative mind (and am seriously jealous of the talent exhibited here).
I am commenting as many as I can, as quickly as I can. Rankings will continue as often as feasible.
