Just before it becomes crunch time for holiday gifts, the Postcard Show pops up for the weekend at The Lab (2948 16th Street). I’ve been assured that the selection of small-format, affordable art in the $1-50 range will knock many names off your shopping list. The show opens before its reception on Saturday evening (shop hours are 1-6, reception from 7-10) and will be DJ’ed by Gina Basso, Phengren Oswald and Deep Sea Authoring in Odin’s Eye Pocket (sorry, no further explanation on that detail). Mini-Market will occupy the Front Gallery with small-format foods by local artists, too!
