This is an interesting time for these stamps to come out. There is quite a lot of symbolism to evaluate. For starters…

Dog Days of Summer - About mid-July through mid-August

Dog Star = Sirius (in Orion Constellation)

Sirius = Scorching (Greek)

= Isis (Egyptian)

Also, I have read that in some areas it was customary for parents to keep children indoors during the festivals and feasts which occurred during this time of year. Gee, I wonder why.
