Most likely, considering the context, yes. But there were posters made during WWII with the slogan “Ждем с победой” (“Waiting for [you to return bringing] victory” or something like that. Here’s one by Nina Nikolayevna Vatolina, for example, maybe there were more).

But it’s not like it really matters lol

The poster says “с Победой!”, literally “With the Victory”. Most likely relates to the victory in WWII in some way, either awaiting it or congratulating on it.
