These were both produced by Hallmark during the 1920s.
04/09 Update: These two Hallmark invitations sold for a pittance compared to what they typically fetch. The invitation in front is more common than the other, yet still usually brings $50-60 alone. The other card, less often seen, usually brings $70-80. What accounts for this weak result? Is small paper losing a bit of its luster? Is it simply be due to the vagaries of eBay?
