This art style is by the artist Stefano Riboli, and it is a mixes of his pinup and vintage advertising.

The v1.0 lora works best at (0.8-1) with the following model: Chef's Matrix Chair & Comimicry(Overall more compatible with many models unlike v2.0) and VAE: vae-ft-mse-840000-ema-pruned.

Update: The v2.0 is more consistent with Stefano Riboli's art style and works best with the model: XenoGASM & Chef's Matrix Chair at weight (0.8). Also the last update on this lora.

I suggest using Centerfold512 or Pinup512 for a more pin-up look:
